Toyota says it will combine EneCoats perovskite solar cells and its own vehicle-integrated solar panel technologies. Enecoat has developed a perovskite module with a conversion efficiency of 19.4%.
EneCoat Technologies, a Kyoto University photovoltaics spin-off company, and Toyota Motor have announced that they will team up to develop perovskite solar cells for vehicle-integrated photovoltaics (VIPV) applications.
“The two companies will continue to promote the development of practical applications by integrating EneCoats elemental technologies for perovskite solar cells and Toyotas vehicle-integrated technologies for solar panels, with the aim of promoting self-sufficiency in renewable energy and contributing to the achieving carbon neutrality," the two companies said in a statement.
EneCoat said Toyota will use the cells it develops and produces with a proprietary deposition technology that enabled the production of a perovskite module with 19.4% efficiency starting in March 2023.
“Using a low-temperature coating process, it is possible to create a highly uniform ultra-thin film as shown in the figure,” the company said. “Taking advantage of the fact that the wet process makes large area surfaces suitable for mass production, we plan to move forward with roll to roll production that can be tailored to the application and scale in the future.”
In April 2022, NGK Insulators, a Japanese network-attached storage (NAS) specialist, acquired an unspecified stake in EneCoat. The Japanese company Green Science Alliance, which specializes in the development of electrode materials for solar cells, also invested an unspecified sum in Enecoat in June.
Toyota declared in March that it had selected Japanese solar cell maker Kaneka as a supplier for the installation of solar cells in one of its electric vehicles. Kanekas solar cells have been recognized for years as the most efficient crystalline silicon photovoltaic device developed at both industrial and research levels.
However, Chinese manufacturer Longi declared last November that it had achieved a power conversion efficiency of 26.81% with an unspecified heterojunction (HJT) solar cell, based on a full-size silicon wafer, in mass production. . |
