Tsutomu Miyasaka

, is a Japanese engineer in electrochemistry best known as the inventor of the perovskite solar cell.

Education Miyasaka graduated from the Applied Chemistry Department of Waseda University in March 1976. He obtained a master's degree in industrial chemistry from the University of Tokyo (UTokyo) in 1978. He was a visiting researcher at the University of Quebec in Canada in 1980 when he was study Ph.D. in synthetic chemistry at the UTokyo.

Career Miyasaka joined Fujifilm after completing his PhD in March 1981, he worked on the development of high-sensitivity films for photo camera films for instant cameras and the development of lithium-ion battery.

Since 2009, Miyasaka has been working on research and development of perovskite solar cell, therefore, he won the Clarivate Citation Laureates in 2017. In 2017 Miyasaka was awarded the Hamakawa award for his contribution in photovoltaic science and technology development.
