PXP Corporation

PXP Corporation is a Japanese green tech startup, based in Sagamihara City, Kanagawa, established in 2020.

PXP is focused on the R&D, manufacturing and sales of next-generation photoelectric conversion devices. It developed flexible solar cells based on perovskites and a type of chalcopyrite that enable lightweight, flexible, thin-film solar cells.

According to the company, the perovskite has superior performance for visible light, and chalcopyrite has superior performance for infrared light, so together they are the most efficient combination of materials in terms of the widest range of wavelengths, so high efficiency more than 30% can be expected from their tandem use. 

PXP explains that chalcopyrite technology, which has already been applied to gigawatt-scale mass production and has been installed in various environments around the world, can be applied to perovskite to achieve high productivity and durability. The perovskite and chalcopyrite it uses are common materials, and they are only used in small amounts. No organic solvents are required. The energy used for production is less than half that of conventional solar panels, making it an environmentally friendly technology.
