Tsutomu Miyasaka (宮坂力, Miyasaka Tsutomu, born September 10, 1953), is a Japanese engineer in electrochemistry best known as the inventor of the perovskite solar cell.[1]

Education

[edit]

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.[2]

Career

[edit]

Miyasaka joined Fujifilm after completing his PhD in March 1981,[3] he worked on the development of high-sensitivity films for photo camera films for instant cameras and the development of lithium-ion battery.[3] However, Fujifilm has discontinued development of lithium-ion battery due to "impossible to make a profit". After being recruited, he became a professor at Graduate School of Engineering at Toin University of Yokohama in 2001.[3]

Meantime in 2004, in response to the promotion of the venture company's founding policy by the mayor of Yokohama City, Miyasaka established Peccell Technologies for solar cell research and served as the representative director until 2009.[3]

He also developed the first photocapacitor.[4][5][6]

Since 2009, Miyasaka has been working on research and development of perovskite solar cell, therefore, he won the Clarivate Citation Laureates in 2017.[7] In 2017 Miyasaka was awarded the Hamakawa award for his contribution in photovoltaic science and technology development.[8]
