In Depth

Key Findings

JinkoSolar, a prominent Chinese solar module manufacturer, has announced a new world record in the development of perovskite-silicon tandem solar cells, achieving an impressive power conversion efficiency of 34.82%. This remarkable efficiency has been rigorously certified by the Shanghai Institute of Microsystem and Information Technology (SIMIT) of the Chinese Academy of Sciences, clearly positioning JinkoSolar as a global leader in next-generation solar cell R&D. The company successfully improved upon its previous record of 34.76% achieved in December 2025, demonstrating a steady gain of 0.06 percentage points in just six months. This highlights the rapid evolution of perovskite-silicon tandem technology and JinkoSolar’s continuous innovation capabilities.

Technical Details

JinkoSolar’s perovskite-silicon tandem solar cell is engineered to surpass the limitations of conventional crystalline silicon solar cells. The technology operates by layering two semiconductor materials with different bandgaps—perovskite and silicon—to efficiently capture photons. The perovskite layer absorbs the high-energy portion of the solar spectrum (e.g., blue light), while the underlying silicon layer absorbs the remaining lower-energy portion (e.g., red light). This complementary absorption maximizes the utilization of the solar spectrum, achieving efficiencies unattainable with single-junction cells. JinkoSolar attributes this record-breaking efficiency to its focus on interface optimization, improvements in charge transport layers, and the development of proprietary perovskite material compositions. Crucially, precise defect control and minimization of carrier recombination losses played a significant role.

Background & Context

The solar photovoltaic industry is relentlessly pursuing technological innovations to accelerate the global transition to sustainable energy. Conventional single-junction silicon solar cells are mature, and their efficiency improvements are nearing physical limits. Consequently, perovskite-silicon tandem solar cells are attracting significant attention as a ‘game-changer.’ The continuous breaking of world records in this field by major manufacturers like JinkoSolar indicates that this technology is moving beyond the research phase and is highly likely to be commercialized in the near future. Tandem technology allows for increased power output per unit area of solar energy systems, offering particular advantages in space-constrained locations and for large-scale projects demanding higher energy yields. This will further enhance the global competitiveness of solar photovoltaics.

Strategic Significance & Outlook

JinkoSolar’s achievement of 34.82% power conversion efficiency significantly advances the commercialization pathway for perovskite-silicon tandem solar cells. The company is actively pursuing a roadmap to deploy this technology at a mass-production scale, aiming to introduce even higher-efficiency and more cost-effective products to the market. While challenges in technology stability, durability, and large-scale manufacturing remain, this latest achievement signals strong confidence in overcoming these hurdles. The widespread adoption of high-efficiency tandem modules could accelerate solar deployment across a broad range of sectors, including residential, commercial, industrial applications, and utility-scale solar farms, making an indispensable contribution to increasing renewable energy’s share in the global energy mix and achieving global decarbonization targets.
