Resumen de: WO2026060917A1
Disclosed are a method for preparing a perovskite solar cell, a solar cell, and a photovoltaic system. In the method for preparing a perovskite solar cell provided by the present invention, a passivation gas is introduced into the etching region during the process of laser etching of a second etched groove and a third etched groove. The passivation gas reacts with Pb2+ in the perovskite layer to form a passivation film covering the etching position of the etched groove. During laser etching, the passivating gas is introduced to form the passivating film covering the etched portion, thus preventing the perovskite material from being exposed to a water and oxygen environment. This accelerates the aging process of the material, thereby reducing the service life and the photoelectric conversion capability of the perovskite module.
