Small molecule donor/polymer acceptor (SD/PA)-type organic solar cells (OSCs) have attracted widespread attention in recent years due to the continuing power conversion efficiency (PCE) growth, near 10%, and the excellent thermal stability for the practical applications. However, the development of SD/PA-type OSCs lags far behind that of polymer donor/small molecule acceptor (PD/SA)-type OSCs, which are also based on the combination of small molecule and polymer, with the PCEs exceeding 18%. The reasons accounting for this great gap are well worth exploring. In this review, we have analyzed the key factors affecting the photovoltaic performances of SD/PA-type OSCs, systematically summarized the research progress of SD/PA type OSCs in recent years, and put forward our own views on the future development of SD/PA type OSCs. Small molecule donor/polymer acceptor (SD/PA)-type organic solar cells (OSCs) recently have received increasing attention due to their excellent thermal stability and the potential for large-scale practical applications. The important factors that limit the photovoltaic performances of SD/PA type OSCs are briefly discussed, and the recent research progress on the SD/PA system is comprehensively summarized.
