Organic solar cell (OSC) is a kind of solar cells which active layer is made of organic materials. Ben-zo[1,2-b:4,5-b']dithiophene (BDT) has become a star molecule unit in organic solar cells donor material field, because its large rigid plane conjugated structure can improve the delocalization of π-electron and π-π interactions between molecules significantly. BDT is also easy to be synthesized and chemically modified. The highest power conversion efficiency (PCE) 9.95% has already been achieved based on BDT unit, which shows an enormous potential application in organic photovoltaic device (OPV). This paper summarizes the research process of BDT-based small molecule organic solar cell (SM-OSC) active layer material in recent years and gives a brief analysis of device performance effects caused by main chain, side chain and terminal group of small mol-ecule.

Key words: benzodithiophene, small molecule, organic solar cells
