Two types of perovskite/crystalline Si tandem solar cell are investigated. Over 29%-conversion efficiency is obtained for two-terminal (2T) perovskite/heterojunction crystalline Si tandem solar cell using 145 um-thick Czochralski (CZ-) Si wafer. For the larger area four-terminal (4T) perovskite/crystalline Si tandem solar cell, we clarified that the based technologies are ready to realize 30%-conversion efficiency with approximately quarter size of industrial crystalline Si solar cell (~64 cm2).
