Perovskite solar cells (prototype modules at Toin University of Yokohama)

Perovskite solar cells are a next-generation solar cell invented by a specially appointed professor at Toin University of Yokohama, who is said to be a promising candidate for both the Nobel Prize in Chemistry and Physics.
Compared to conventional silicon solar cells, it has the following characteristics, so it can be expected to be deployed in various applications, and it can be said to be the trump card for expanding renewable energy.

・Thin, light, bendable
・It can be made with printing technology that can be applied and dried.
・Power generation can be generated even in weak light (slightly cloudy weather, rainy weather, indoor)
・Most of the raw materials can be procured in Japan

Various applications can be conceivable by utilizing the characteristics of perovskite solar cells.
・By attaching it to the back of the smartphone, it eliminates the need to carry a mobile battery.
・By attaching it to a remote control or controller, there is no need to replace batteries.
・By attaching it to clothes, it is possible to generate electricity while moving.
・It can be installed in places that cannot be handled by conventional silicon-type solar cells, such as walls and curved surfaces
In this way, next-generation solar cells, including perovskite solar cells, have the potential to change the future.
