Perovskite tandem solar cells

Manufacturers and research institutes participating in the perovskite tandem solar cell market in Japan

Since the inception of the Feed-In Tariff program, demand for solar cells has increased rapidly in Japan. Assuming that solar cell modules last 20 years, the replacement demand for solar cells is expected to surge by 2032. To meet this demand, it is crucial to produce domestic perovskite solar cells (PSCs) and perovskite tandem solar cells (tandem PSCs). This is the last chance to revitalize the domestic solar cell industry. To seize this opportunity, mass production of tandem PSCs is necessary. Therefore, domestic manufacturers are required to speed up their product development. 
Based on interviews with domestic manufacturers and universities developing tandem PSCs, this report examines and analyzes trends of the market, technology, market players and R&D institutions, as well as the environment and future prospects of the perovskite tandem solar cell market.

I. Prospects and Strategies in the Perovskite Tandem Solar Cell Market

• 2032, Which is 20 Years Since the Inception of the Feed-In Tariff program, is the Last Chance for Japanese Solar Cell Industry to Revitalize.
• To achieve the target of "23–29% solar power in the energy mix by 2040" set forth in the 7th Basic Energy Plan, perovskite tandem solar cells with high power-to-area efficiency are indispensable.
• Perovskite/Si is expected to capture replacement demand for crystalline silicon solar cells.
• The cumulative installation volume of perovskite solar cells, including perovskite tandem solar cells, is projected to reach 12.5 GW by 2040.
• To secure an early market share, domestic companies should target applications where foreign competitors are yet to enter due to high barriers or those with 10 years of useful life.
• Bringing crystalline silicon cell development back to Japan requires long-term support for human resource development through collaboration between industry, academia, and the government.
• Lightweight, flexible all-perovskite tandem solar cells (APTSC) and chalcopyrite solar cells, or CIGS, are expected to be adopted for use in aircraft, such as high-altitude platform stations (HAPS).
