Perovskite-perovskite-silicon triple-junction solar cells have technical potential to reach 44.3% efficiency

A German research team has investigated the optical properties of perovskite/perovskite/silicon triple-junction cells and has found these devices may have a practical efficiency potential of 44. 3% assuming idealized electrical parameters. These cells may also potentially achieve a fill factor of 90. 1%. A group of researchers in Germany has developed a comprehensive optoelectrical simulation model for triple-junction solar cells based on subcells relying on perovskite, perovskite, and crystalline silicon, respectively. The model is intended to define an efficiency roadmap for improving the optical ...
