For thin-film perovskite photovoltaic cells that can be bent, Japan's Ministry of Economy, Trade and Industry has set a government target of introducing 20 gigawatt-hours in 2040, which is equivalent to the electricity consumption of approximately 5.5 million households. Japan strives to use perovskite batteries to provide around 10% of household electricity. To achieve the goal, in addition to supporting research on mass production technology, the Japanese government will also discuss plans to increase demand. Among renewable energy sources in Japan, photovoltaic power generation is the most popular. Photovoltaics accounted for 9.8% of the power supply composition in 2023, and the installed capacity as of the end of December 2023 was 73 gigawatts. If current electricity demand is assumed, the 2040 installed target for perovskite batteries is equivalent to nearly 3% of the power supply.
