SHANGHAI, April 18, 2026 /PRNewswire/ — JinkoSolar, the global leading PV and ESS supplier, recently published three research papers in succession within a single month in Nature Energy, one of the premier journals in the field of energy research. This series of papers showcases JinkoSolar’s multiple major breakthroughs in TOPCon and perovskite tandem cell technologies.

26.66%! Setting a New Record for Industrial-Scale TOPCon Cell Conversion Efficiency

JinkoSolar, in collaboration with the research team from the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, successfully developed a dual-sided electrical synergy optimization strategy. This approach achieved a certified efficiency of up to 26.66% on M10-sized silicon wafers, setting a new efficiency record for industrial-scale TOPCon cells and significantly narrowing the gap between industrial-scale TOPCon cells and the theoretical efficiency of 29.4%.

Additionally, the research reduced carrier transport losses through a high-resistance boron emitter on the front side and an optimized fine-line grid design, while the back side employs an innovative double-layer tunneling silicon oxide/polysilicon structure on the rear side to effectively suppress performance degradation caused by silver paste puncture. Furthermore, by utilizing localized polysilicon thinning technology, the research achieved outstanding performance metrics, including an open-circuit voltage of 744.6 mV, a fill factor of 85.57%, and a bifaciality of 88.3%. This achievement provides a feasible and comprehensive solution for narrowing the efficiency gap between TOPCon cells and the theoretical limit, significantly enhancing the core competitiveness of TOPCon technology in the future photovoltaic market.

Certified Efficiency of 32.73%! Paving the Way for Scalable Compatibility of Perovskite/TOPCon Tandem Cells

JinkoSolar, in collaboration with the research team from Soochow University, has successfully developed a full-size bifacial TOPCon crystalline silicon solar cell with a certified photoconversion efficiency of 26.34%. This research abandons the traditional TOPCon cell design featuring a boron-diffused emitter on the front surface. Instead, it innovatively introduces patterned n-type TOPCon finger contacts on the front surface while retaining the full-area p-type TOPCon contact on the back. By localizing the polycrystalline silicon contact area, this structure significantly reduces parasitic absorption and recombination losses on the front surface, achieving a certified efficiency of 26.34% and significantly improving the open-circuit voltage.

Furthermore, to address the issues of poor contact performance and susceptibility to metal paste corrosion in P-type TOPCon, a “polysilicon/silicon dioxide/polysilicon” double-layer composite structure was designed. Combined with optimized rear-side polishing and a specially formulated silver paste, this structure not only achieves extremely low contact resistance and recombination current but, more importantly, the ultra-thin oxide layer in the middle effectively prevents silver crystal spikes from penetrating the silicon substrate, significantly enhancing the device’s reliability and high-temperature resistance. In the future, by improving the precision of laser patterning to further narrow the finger width and introducing localized contacts on the back side to reduce the polycrystalline silicon layer thickness, parasitic absorption can be reduced, and mass production efficiency is expected to approach 27%.

Using a high-efficiency bifacial TOPCon cell with a textured front surface as the bottom cell, the research team fabricated a monolithic perovskite/TOPCon tandem cell, achieving a certified efficiency of 32.73% and a high open-circuit voltage of 1.961 V. These results not only set a new performance record for this class of tandem cells but also demonstrated excellent long-term operational stability (maintaining 80% of the initial efficiency after 2,000 hours), proving the immense potential of this TOPCon technology route in tandem applications. They also provide a scalable and industrially compatible technical pathway for the development of higher-efficiency TOPCon and perovskite/TOPCon tandem photovoltaic modules.

32.76%! Breaking Through the Efficiency Barrier for Industrial TOPCon Silicon-Based Perovskite Tandem Cells

To address the critical challenge of rapid perovskite crystallization and film quality degradation caused by the high thermal conductivity of industrial thin silicon substrates, JinkoSolar, in collaboration with the National University of Singapore and other research institutions, innovatively proposed a strategy to regulate the major organic cation (FA⁺) using a dual-mode-coupled ligand (MBT), successfully achieving effective control over crystallization kinetics. A perovskite/TOPCon tandem solar cell fabricated using this strategy was certified by the National Photovoltaic Industry Metrology and Testing Center (NPVM) with a conversion efficiency of 32.76%, approaching the current efficiency record for tandem photovoltaic cells. Additionally, the cell maintained 91% of its initial efficiency after 1,700 hours of continuous operation, demonstrating excellent long-term operational reliability.

This research is of significant importance as it achieves high efficiency (certified at 32.76%) in TOPCon silicon-back-contact cells, which hold the greatest potential for market dominance. Not only does it elevate the efficiency of perovskite/TOPCon tandem cells to new heights, but more importantly, it provides critical scientific insights and a practical pathway for integrating high-performance perovskite materials from the laboratory with market-dominant TOPCon silicon technology, marking a solid step toward the mainstream industrialization of perovskite/ crystalline silicon tandem technology toward mainstream industrialization. In the future, this strategy is expected to be combined with solution-based production processes — which offer the potential for large-scale fabrication and low costs — to drive the industrial application of these research findings.

SHANGHAI, April 18, 2026 /PRNewswire/ — JinkoSolar, the global leading PV and ESS supplier, has officially launched a lightweight module solution specifically designed for low-load-bearing roofs—the Jinko “Light Diamond” lightweight, high-strength module, based on its Tiger Neo 3.0 technology platform.

Module weight: 16.2 kg
Module dimensions: 1980 × 1134 × 30 mm
Weight density: 7 kg/m²— 40% weight reduction compared with conventional double-glass modules (12.2 kg/m²);
Maximum power: 560 W;
Maximum module efficiency: 24.94%
Applications: Suitable for older factory buildings, temporary structures, light-gauge steel roofs, power plant coal sheds, and buildings with load restrictions.

Five Key Advantages:

Advantage 1: Ultra-Lightweight with Guaranteed Strength

JinkoSolar’s “Light Diamond” lightweight, high-strength modules weigh only 7 kg per square meter, representing a weight reduction of over 40% compared to conventional double-glass modules. The total module weight for a 1 MW project is only 28.6 tons, a reduction of approximately 20 tons compared to BC double-glass modules. This means that a large number of roofs that previously required reinforcement or were unsuitable for installation can now be directly fitted with solar panels without any structural modifications.

Advantage 2: 24.94% High Efficiency—Lightweight and High-Performance

A common flaw among most lightweight modules on the market is that they prioritize weight reduction at the expense of power generation efficiency. JinkoSolar’s “Light Diamond” lightweight, high-strength modules break this trade-off.

JinkoSolar’s “Light Diamond” lightweight, high-strength modules deliver a maximum power output of 560 watts and an ultra-high efficiency of 24.94%, whereas flexible modules or BC composite modules only reach 450 to 460 watts—a single-module power increase of over 100 watts. This means a higher-capacity solar power plant can be installed on the same roof area. More importantly, the higher power output directly leads to optimized system costs: fewer modules are required, reducing Balance of System (BOS) costs for mounting structures, cables, combiner boxes, and other components; installation time is shortened, lowering labor costs; and overall BOS costs are further reduced by 3% to 5% compared to conventional lightweight solutions.

This is not a lightweight module born of compromise, but a high-efficiency module that takes performance to the next level.

 Advantage 3: Reduced Weight Without Compromising Quality—Backed by a 30-Year Power Warranty

The key concern with lightweight modules is whether their reduced weight compromises reliability. JinkoSolar’s “Light Diamond” lightweight, high-strength modules address this concern with technology and data.

In terms of structural reinforcement, the modules utilize 1.6mm lightweight glass to reduce weight while maintaining light transmittance; the frame features reinforced channel design with increased thickness, enhancing overall mechanical strength; and the encapsulation process uses reinforced adhesive film, significantly improving sealing performance, resistance to humidity and heat, and resistance to micro-cracks.

In terms of load certification, the maximum front-side load capacity is 3,600 Pa—equivalent to withstanding 3.6 meters of snow accumulation—and the module can withstand impacts from 25mm hailstones without damage. The maximum back-side load capacity is 2,400 Pa, equivalent to withstanding Category 12 winds. In the face of extreme weather, it provides a robust safety barrier.

In terms of long-term reliability metrics, the temperature coefficient is -0.26%/°C, resulting in lower power generation losses at high temperatures; the power output warranty spans 30 years, which is 12–15 years longer than that of flexible or composite modules; first-year degradation does not exceed 1%, with annual degradation of 0.35%, both of which outperform industry averages.

Advantage 4: Save Money, Time, and Effort

The lightweight design of JinkoSolar’s “Light Diamond” lightweight, high-strength modules not only reduces physical weight but also systematically optimizes total lifecycle costs.

Compared to conventional module reinforcement solutions, JinkoSolar’s “Light Diamond” lightweight, high-strength modules save approximately 0.5 yuan per watt in reinforcement costs, equivalent to a savings of about 500,000 yuan per MW. The construction period is reduced from over 40 days to 8–10 days—a 75% reduction. There is no need to halt production, thereby avoiding operational losses, and the approval process is simplified, eliminating the need for structural modification approvals.

Taking a 1 MW project as an example, the savings on reinforcement costs amount to approximately 500,000 yuan, the construction period is shortened by more than 30 days, and the avoided production downtime losses—which can reach hundreds of thousands of yuan depending on the company’s scale—significantly boost the project’s internal rate of return (IRR) and markedly shorten the payback period. For retrofit projects involving older factory buildings, the greatest advantage of Jinko’s “Light Diamond” lightweight, high-strength modules is that installation can proceed without halting production; companies can maintain normal operations while the solar power plant is installed on the roof simultaneously, ensuring both objectives are met.

Advantage 5: Strong Demand, a Blue Ocean Market

According to industry statistics, China has over 6 billion square meters of existing commercial and industrial rooftop space, with load-restricted roofs accounting for more than 30% of this total—representing a potential market of nearly 2 billion square meters. Based on an installation density of 100 watts per square meter and a system cost of 1.5 yuan per watt, the theoretical installation capacity exceeds 200 GW, with a market size surpassing 300 billion yuan.

The renovation of old factory buildings, the upgrading of cultural and creative parks, and distributed solar systems on light-gauge steel roofs—these scenarios that were previously unsuitable for installation are now becoming a new blue ocean for PV growth. Whoever can be the first to deliver truly reliable products will be able to capture this market.

Application Scenarios

1) Renovation of Old Industrial Buildings: This is the primary application scenario. Industrial buildings constructed in the last century, as well as power plant coal sheds, carports, and simple rural supermarkets, often have limited roof load-bearing capacity and structurally deteriorated roofs that cannot safely support additional weight. Jinko’s “Light Diamond” lightweight, high-strength modules can be installed without structural reinforcement and do not disrupt production during renovation, making them the preferred solution for the green retrofitting of old industrial buildings.

2) Cultural and Creative Parks and Commercial Complexes: With insufficient roof load-bearing capacity, the need to maintain operations, and aesthetic requirements, Jinko’s “Light Diamond” lightweight, high-strength modules—which are lightweight, efficient, and reliable—are a perfect fit for these scenarios.

3) Light-Gauge Steel Roofs and Color-Coated Steel Sheet Roofs: Light-gauge steel roofs, commonly used in modern industrial facilities, inherently lack sufficient load-bearing capacity. Jinko’s “Light Diamond” lightweight, high-strength modules, weighing just 7 kg per square meter, enable the installation of solar panels on these roofs.

4) Special buildings with load restrictions: Such as space frame structures, arched roofs, and agricultural greenhouses, Jinko’s “Light Diamond” lightweight, high-strength modules can easily adapt to these structures.
