“…Among the metal oxides, ZnO is widely used ETL in OSCs due to its high transmittance, mobility and conductivity . There are different kind of routes for deposition or preparation of ZnO ETL such as spray pyrolysis, sputtering, nanoparticle synthesis, sol–gel method, and so on. , Sol–gel is the most preferred and used technique with the advantages of easy solution processing at low temperature, low cost, uniform thickness throughout the layer, and compatibility for large-area deposition. − Different ETLs and performance in the OSCs are illustrate in the Table .…”

The emergence of nonfullerene small-molecule acceptors (NFSMA) with the advantages of synthetic versatility, high absorption coefficient in wide wavelength range, and high thermal stability has attained the power conversion efficiency (PCE) exceeding 19% for resulted organic solar cells (OSCs) with the optimization of interface engineering and active layer morphology. Interfacial layers including both hole transporting layer (HTL) and electron transporting layer (ETL) are equally important in the OSCs for facilitating electron and hole extraction from the bulk heterojunction (BHJ) photoactive layer by the respective electrodes. In this Review, we summarize the recent progress in the materials used as HTL and ETL in conventional and inverted OSCs on the basis of their effect on the PCE. Finally, the prospects of HTL and ETL materials for NFSMA-OSCs will be provided.
