Abstract

Cu(In_1-xGa_x)Se₂ (CIGS)-based solar cells have emerged as one of the most promising candidates for high-efficiency low-cost thin-film solar cells, and a significant improvement in solar cell performance has been reported with conversion efficiencies as high as eta=19.9%, though the efficiencies of commercial modules are limited to eta=11-12%. In Japan, the efficiency goal for 2030 is set to be eta=25% for small area cells and eta=22% for large-size modules, therefore improvement in conversion efficiencies for both cells and modules are required.
