As the number of places suitable for solar power generation decreases year by year, electric appliance manufacturers are developing technology to apply special materials to films and building materials instead of conventional panels so that power can be generated even on the walls and windows of buildings. Is progressing.

In solar power generation, it is common to arrange solar panels on a large land or install them on the roof, but the number of suitable places is decreasing year by year.



Under these circumstances, Toshiba is developing a film-type solar cell with a thickness of about 1 mm.



It is made by applying a material with a special crystal structure called perovskite to a film and it can be bent, and it can be installed in various places such as building walls and uneven roofs.



Since the power generation efficiency is almost the same as that of conventional solar panels, we are aiming for commercialization by the end of 2025.



Kenji Totori, Senior Expert of Toshiba R & D Center, said, "We can generate electricity without destroying the cityscape without the need for a special place. We would like to proceed with further research, such as extending the service life."



In addition, Panasonic is researching the technology of applying perovskite film to building materials by applying the printing technology of printers.



Kyocera has also started to develop such solar cells, and the development of technology is progressing as it will be the "trump card" for the expansion of the introduction of renewable energy among electric appliance manufacturers.
