According to Japanese media reports, the research team composed of the Japanese Institute of physics and chemistry and the University of Tokyo reported in the British science journal Nature energy (Electronic Edition) on 18 June that they had developed ultra-thin solar cells with scalability and washability.

It is reported that users can attach it to their clothes and use it as a power supply for wearable machines.

According to the report, the Institute's researcher Yoshiro Fukuda and Professor ryuno Kawabata of Tokyo University applied organic compounds with semiconductor properties on extremely thin polymer films to make solar cells. It is reported that the thickness is only 3 microns, and even bending and pressing can work normally.

"If you stick it on clothes like shirts, it may also be used as a medical device to measure blood pressure and body temperature all the time, to detect diseases early, and to power machines such as thin smartphones integrated with clothes," Fukuda said.
