Toyota Motor Corp. has announced a partnership with a startup company based in Kyoto Prefecture to develop next-generation perovskite solar cells (PSCs). These cells, which are expected to be used in automobiles by 2026, offer several advantages over traditional crystalline silicon solar panels used on house roofs. They are lighter, thinner, and flexible, making them suitable for fitting the shape of a car roof.

PSCs are created by coating a panel with a special organic compound that absorbs light. When used as a power source in electric vehicles, they are expected to extend the cruising range. Toyota and the startup company, EneCoat Technologies Co., signed a contract for joint development in May. EneCoat, supported by Kyoto University, specializes in applying uniform coats of organic compounds and will focus on developing materials and power generation elements. Toyota, on the other hand, will concentrate on developing the technology to install the cells on automobiles.

Toyota already offers optional installations of solar cells for its electric vehicles and plug-in hybrids. The solar cells incorporated into their latest Prius plug-in model, launched in March, can generate enough electricity to power the car for over 1,200 kilometers annually. Toyota aims to further improve solar cell performance as part of its commitment to decarbonize its vehicles.

This partnership between Toyota and EneCoat Technologies represents an exciting step towards the advancement of perovskite solar cell technology and its integration into the automotive industry. By harnessing the potential of PSCs, Toyota aims to enhance the sustainability and energy efficiency of its vehicles, contributing to a greener future.
