Japan to promote perovskite solar cells

Japan’s industry ministry is considering promoting the use of perovskite solar cells to cover 20 gigawatts of electricity by 2040.

The plan is part of efforts to expand the use of renewable energy sources by supporting the introduction of next-generation technologies at a time when the country is racing to reduce carbon emissions.

The ministry aims to include the plan in the country’s basic energy program that the government will update in fiscal 2024, which ends next March.

The existing energy program calls for increasing the share of renewable energy sources to 36-38 percent of power generation in fiscal 2030, compared with 22.9 percent in fiscal 2023.

The new program, which sets targets for fiscal 2040, is expected to further increase the share of renewables in anticipation of the expansion of perovskite solar cells.
