Microcrystalline tandem

Lowering system prices is key to diffusion of solar cells. Accordingly, mass production of solar cells using thin-film silicon technology or composites is attracting attention as a substitute for crystalline solar cells. In particular, MHI’s proprietary technologies (for production of high-speed, large-area films) are highly valued by NEDO and peers.
