Article Synopsis
- - All-perovskite tandem solar cells could exceed the efficiency limits of traditional solar cells, but their performance is currently restricted by defects that cause energy losses in the material.
- - Researchers developed a method using a surface polishing agent and a passivator to fix defects in Sn-Pb mixed perovskite films, improving the film quality and reducing non-radiative energy loss.
- - The optimized solar cells achieved power conversion efficiencies of 22.65% and 23.32%, with a certified efficiency of 28.49% for two-junction all-perovskite tandem cells, indicating significant progress in solar technology.
Wide-bandgap (WBG) perovskite solar cells (PSCs) have been widely used as the top cell of tandem solar cells. However, photoinduced phase segregation and high open-circuit voltage loss pose significant obstacles to the development of WBG PSCs. Here, a two-step small-size A-site and large-size X-site incorporation strategy is reported to modulate the lattice distortion and improve the film quality of WBG formamidinium-methylammonium (FAMA) perovskite films for photostable PSCs based on two-step deposition method.
