Next-generation photovoltaics with high performance

In our laboratory, next-generation high-performance photovoltaics using organometalhalide perovskite have been investigated. We obtained 25.9% and 25.6% of energy conversion efficiencies using inverted structure and methyl ammonium-free normal structure, respectively. Furthermore, we achieved more than 20% of the energy conversion efficiency of the flexible monolithic minimodule (photograph 1).
Dye-sensitized solar cells, quantum dot solar cells, and energy storable solar cells (photograph 2) have also been developed. Various basic and applied researches on the photoenergy conversion will open the door of sustainable and carbon neutral society.
