摘要
Perovskite solar cells(PSCs) have been developed rapidly recently, and efficient planar PSCs are regarded as the most promising replacement of the Si solar cells.However, the environmental instability of perovskite solar cells is an important issue that must be solved.We demonstrated that the surface passivation of electron transport layer(ETL) of PSCs can reduce the density of electron traps and suppress photocatalytic decomposition of perovskite films.Due to the improved electronic property of ETL, the planar heterojunction PSCs exhibit negligible hysteretic J-V behavior.The initial performance and long term stability in atmospheric environment under continuous illumination are also effectively improved.The efficiency just dropped from 17.2% to 15.03% after 250 h continuous exposure under full spectrum simulated sunlight in air.Fabrication of highly efficient planar PSCs with improved stability provides a pathway for commercialization of PSCs.
