摘要: The electron transport layer (ETL), which also serves as the hole-blocking layer, is a key component in planar perovskite solar cells (PSCs). The commonly used ETL is an anatase-TiO2 (an-TiO2) film due to its excellent optical transmittance, chemical stability and semiconducting characteristics. Nevertheless, its rough surface and plenty of surface defects often lead to a substandard perovskite film and large J–V hysteresis. Herein, a novel low-trap-density ETL is developed by surface modification of the an-TiO2 film using small …
