Abstract

The optimization of perovskite interfaces is an effective method to boost the device efficiency. In this review, we have reported an effective surface passivation method to improve the efficiency of the PSCs by heating the PC60BM ETL layer. The obtained results shows that device performance was effectively improved after an annealing treatment of the PC60M layer at 100 °C for 10 min. Furthermore, this improvement is due to the passivation of structural defects at the perovskite/ETL interface. Moreover, the annealing treatment of the PCBM layer could enhance electron extraction and suppressed charge recombination by smoothing the surface of the perovskite and decreasing the surface traps, which has enhanced the device efficiency to 10.22%.
