Miyasaka won the 2024 Japan Academy Prize for his outstanding contribution to the field of solar energy by discovering organo-lead halide compounds as absorbers for perovskite solar cells, which exhibit energy conversion efficiencies comparable to those of the most efficient crystalline silicon solar cells. His research focuses on the development of new perovskite materials to enhance efficiency and device stability.

His work in perovskite solar cells has spurred global research efforts, leading to rapid improvements in efficiency of the solar cells. Miyasaka has shown that a key factor in enhancing the efficiency of solar cells is the solution- based crystallization process, which improves the quality of perovskite polycrystalline films. Miyasaka’s work is expected to significantly contribute to the realization of a carbon-neutral society.
