Next-generation photovoltaics with high performance

In our laboratory, next-generation high-performance photovoltaics using organometalhalide perovskite have been investigated. We obtained 24.4% and 24.9% of energy conversion efficiencies using potassium-doped perovskite and methyl ammonium-free perovskite, 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 photoenergyconversion will open the door of sustainable and carbon neutral society.
