摘要
Perovskite solar cells(PSCs) have attracted tremendous attention in recent years due to the high device performance and the unique optoelectronic properties of perovskite materials [1].Charge carrier balance is critical for high performance perovskite solar cells [2].To improve the balance, one ongoing focus is to manipulate the charge carrier transport process by employing appropriate interface engineering [3].Here, we report the solvent treated PEDOT:PSS and additive modified PCBM as the hole selective contact(HSC) and electron selective contact(ESC), respectively, resulting in accelerated and balanced charge carrier transport within the device [4].As a consequence, charge carrier accumulation and recombination at the perovskite/selective contact interfaces were suppressed, leading to a power conversion efficiency(PCE) of 18.72% for a champion cell with a stabilized power output of 17.70% at the maximum power point.The optimized devices also exhibited negligible current density-voltage(J-V) hysteresis and improved reproducibility.
