Abstract: Bulk heterojunction polymer solar cells (PSCs) have attracted enormous attention due to their various advantages of low-cost, favorable flexibility and feasibility for large-scales roll-to-roll fabrication. Considerable progress has been made in researches of PSCs in recent years. Nevertheless, several scientific issues and challenges of PSCs like poor charge carrier separation, transfer and collection, have been hindering their application in large-scale commercial production. Stable and effective interfacial contact plays a critical role in enhancing the performance of PSCs. This article summarizes the functions and classifications of the interfacial layer in polymer solar cells, including inorganic interlayers, fullerene derivatives, water/alcohol-soluble neutral conjugated polymers, water/alcohol-soluble ionic conjugated polymers electrolyte, hyperbranched small molecule electrolytes and perylene diimide derivatives.
