By developing a new film forming method for a thin-film-type perovskite solar cell that uses a material in the crystal structure referred to as perovskite, Toshiba Corporation Corporate Research & Development Center and Toshiba Energy Systems & Solutions Corporation have achieved the world’s highest*1 energy conversion efficiency of 15.1%.g
Because fragile this solar cell has the characteristics of being lightweight, thin, bendable fragile, and break-proof, which are not found in conventional solar cells, it can be installed on roofs with a low load resistance (of a factory, gymnasium, vinyl house, etc.), on which conventional solar cells are difficult to install, as well as on building exterior walls, windows, and so on.
If this solar cell with an energy conversion efficiency of 15.1% is installed on even some of the building rooftops and walls in Tokyo’s 23 wards, power generation equivalent to two nuclear power plant units (equivalent to two-thirds of the annual household power consumption in Tokyo’s 23 wards) can be expected*2. Part of this achievement was obtained from the results of a project commissioned by the New Energy and Industrial Technology Development Organization (NEDO).
