Abstract: Due to their simple manufacturing processes, low-temperature film-forming technology, negligible hysteresis, and suitability for preparation of multi-stack devices with conventional solar cells, inverted perovskite solar cells (PSCs) have been extensively researched. In the past se-veral years, the power conversion efficiency of inverted PSCs has increased from 3.9% to 25.37%. As a major component of PSCs, the electron transport layer (ETL) plays a critical role in extracting and transporting carriers, blocking holes, modifying energy levels, and preventing charge recombination. Because of their ease of synthesis and purification, high electron mobility, good solubility, and excellent chemical/thermal stability, organic materials such as fullerene and its derivatives, perylene diimide, and naphthalimide have been most commonly used in the ETLs of inverted PSCs. This review mainly introduces the research status of organic ETLs, modification methods for improving device performance by ETL doping, and interface modification in inverted PSCs, thus providing basic theoretical guidelines for developing new organic ETLs.
