CTOnews.com June 27 news, according to "Japan Economic News" reported that Toyota Motor and Kyoto University from the Japanese start-up Enecoat Technologies announced today, will jointly develop perovskite photovoltaic cells, and strive to 2030 will be mounted on the roof of pure electric vehicles and other parts.

▲ Enecoat Technologies Toyota has provided optional services for installing photovoltaic cells on the roof of some new energy vehicles. For example, the Prius launched in 2023 can carry silicon panels of about 1 square meter at a price of 286,000 yen (CTOnews.com Note: Currently about 14443 yuan). Under normal weather conditions, the panel can generate the electricity needed to travel about 1200 kilometers per year.

Toyota and Enecoat started joint research and development of vehicle panels in May. The current power generation efficiency is basically the same as that of silicon panels, but it is expected to increase by 50% in the future. This is also Toyota's first joint research and development plan with external enterprises on perovskite photovoltaic cells.

Toyota renewable energy director Masuda Taizo said that if the engine hood and other parts other than the roof are also installed with perovskite panels, theoretically, the power generation can be increased to up to three times the current level, that is, 3600 kilometers can be supported. Ordinary private cars travel about 10,000 kilometers a year, which means that one-third of their electricity consumption can be provided by solar energy.

Enecoat President Kato said that perovskite-type photovoltaic cells have fewer manufacturing processes than silicon and are expected to reduce costs. At the same time, this battery panel is also easy to bend, more suitable for the more complex shape of the body. However, at present, there are still many challenges in the automotive application of this technology, such as the mass production of tens of centimeters of large panels required for vehicles has not yet begun, and the impact of body vibration and rain on battery durability is also a problem that needs to be considered and solved.

According to data from Japan's Fuji Economy, the global market size of perovskite photovoltaic cells will reach 1 trillion yen by 2035 (currently about 50.5 billion yuan), 31 times that of 2022. At present, Japanese companies such as Seizumi Chemical Industry, KANEKA and Toshiba are striving for commercial use as soon as possible, while Chinese companies are also actively exploring this market.
