Perovskite-silicon tandem solar cell based on wide-bandgap top device achieves 33.10% efficiency

Researchers in China have integrated a wide-bandgap perovskite solar cell with a hybrid back contact device in a four-terminal tandem cell that achieves high efficiency and stability. Key for the strong performance was a new surface passivation strategy that the research group adopted for the top cell. Researchers at the Huaqiao University in China have fabricated a four-terminal (4T) perovskite-silicon solar cell with a top cell based on a perovskite material with an energy bandgap of 1. 67 and lower surface defects. The scientists utilized a surface reconstruction method to remove the surface ...
