Contributing widely from construction materials to modules
Photovoltaic cells are a clean, inexhaustible energy source, and active R&D is being conducted to achieve goals such as boosting performance and lengthening service life. Regarding the next-generation of photovoltaics, such as Perovskite and organic thin-film types, which can be fabricated at lower cost than the current mainstream silicon type, we support R&D to achieve further improvement in generation/conversion efficiency, through approaches such as evaluation of various materials and observation of cell structure.
