Honda Soltec Co., Ltd. will this year release a new thin-film solar cell with an even more compact design than the current model to allow efficient installation on a wide range of roof shapes. The module conversion efficiency of the new solar cell module is expected to exceed 13.0%, ranking it among the world’s most efficient CIGS-based thin-film solar cells. (Earlier post.)
CIGS solar cells consist of a thin film made from a compound of copper, indium, gallium and selenium
The performance of the photosensitive CIGS layer has been improved and the surface area of the surrounding frame and other non-photosensitive portions reduced, resulting in approx. 10% increase in module conversion efficiency compared to the current model. This results in more power generated from the same installed surface area.
The new model is more compact, with only approximately two-thirds the module surface area of the current model, allowing it to be installed in limited space on a wide range of roof shapes. This will facilitate the efficient installation of more thin-film solar cells in a variety of locations.
The prototype manufactured using existing Honda Soltec equipment achieved a module conversion efficiency of 13.0%. Honda is working to further improve module conversion efficiency as it brings the product to market.
