摘要
Recently, Perovskite solar cells(PSCs) are one of the most promising lab-scale technologies to deliver inexpensive solar electricity.Low-temperature planar PSCs are particularly suited for large-scale manufacturing.Here, we propose a simple, solution-processed technological approach for depositing SnO_2 layers.The use of these layers in planar PSCs yields a high stabilized power conversion efficiency close to 13% with no obvious hysteresis.The all layers of the PSCs were fabricated at low temperature.This approach represents an advancement in the understanding of the role of electron selective layers on the efficiency and stability of PSCs.Therefore, the newly proposed approach constitutes a simple, scalable method paving the way for industrialization of perovskite solar cells.
