Certified by the US National Renewable Energy Laboratory (NREL), LONGi’s self-developed large-area (260.9 cm²) crystalline silicon-perovskite two-terminal tandem solar cell achieved conversion efficiency of 33 percent, setting a new global efficiency record for large-area tandem cells.
In this study, we present a groundbreaking achievement with a record efficiency of 26.6% for p-type silicon solar cells employing SHJ technology, utilizing a commercial-size p-type silicon wafer.
At SNEC 2025, LONGi’s crystalline silicon-perovskite tandem solar cell achieved groundbreaking 33 percent efficiency on an ultra-large area of 260.9 cm² through material innovation and structural optimization.
Here, we present the progresses in silicon heterojunction (SHJ) solar cell technology to attain a record efficiency of 26.6% for p-type silicon solar cells. Notably, these cells were manufactured on M6 wafers using a research and development (R&D) production process that aligns with mass production capabilities.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
The breakthroughs include a 33 percent conversion efficiency for a commercial-size silicon-perovskite tandem solar cell and 26 percent efficiency for a crystalline silicon module.
