As commercialization of perovskite solar cells draws near, demonstrations of their installation on buildings are expanding.
Aisin announced on March 31st that it has begun in-house demonstrations at its Anjo Factory in Anjo City, Aichi Prefecture.
In the demonstration, perovskite solar cells will be installed on the four walls and roof of facilities on the factory site, and the system power generation evaluation, construction evaluation, and operation with grid connection will be evaluated. The power output is expected to reach approximately 30kW by the end of September. This is said to be the first grid connection using perovskite solar cells in Japan.
The team will verify differences in power generation depending on the direction and solar radiation intensity, as well as construction time, costs, and maintenance, and will identify issues and consider solutions for social implementation. In the future, they will increase the number of installation locations and conduct demonstrations both inside and outside the company, promoting research and development for early practical application.
Aisin's perovskite solar cells are characterized by their high power generation efficiency, achieved through more than 20 years of research and development into solar cells, and their high durability, achieved through a unique film structure using thin glass, utilizing the manufacturing capabilities they have cultivated in the manufacture of automotive parts.
Sekisui Chemical and its group company Sekisui Solar Film (Osaka City), which designs, manufactures, and sells film-type perovskite solar cells, also announced on the same day that they will participate in a perovskite solar cell research and development project led by Fukushima Prefecture.
The project will install perovskite solar cells at three public facilities in Fukushima Prefecture and verify the suitability of the installation locations, the equipment required for installation, and the installation method. The generated electricity will be used for storage batteries, digital signage, etc. The installation locations are approximately 60m2 of the lawn area of the rotary in front of the J Village Center House, approximately 30m2 of the roof of Azuma Athletic Park's First Gymnasium, and approximately 40m2 of the wall at the front entrance of the Fukushima Prefectural Museum. The total power generation output will be approximately 10kW.
In the future, the team will select several candidate sites for model installation that can take advantage of the characteristics of film-type perovskite solar cells, targeting roofs, walls, and uneven ground of highly public facilities in Fukushima Prefecture, and consider the concrete possibility of introduction.
