Kaneka Corporation has achieved in a NEDO project the world’s highest conversion efficiency of 26.33% in a practical size (180 cm2) crystalline silicon solar cell.
This achievement breaks the world record of 25.6% by ~0.7%, exceeding 26% for the first time in the world. NEDO and Kaneka Corporation have been working to develop high conversion efficiency crystalline silicon solar cells targeting LCOE reduction.
Improving the efficiency of silicon-based solar cells beyond the 29% limit requires the use of tandem structures, which potentially have a much higher (~40%) efficiency limit. Both perovskite/silicon and III-V/silicon multijunctions are of great interest in this respect.
The previous record *4 for the conversion efficiency of crystalline silicon-based solar cells of a practical size (100 cm² and over) was 24.7%, as announced by Panasonic in February 2013 (cell area: 101.8 cm²). The new record is 0.9 points higher and the first to break through the 25% barrier for practical size cells.
