As a promising alternative to fossil energy, the development of photovoltaic energy is pivotal to the completion of carbon neutrality. Comparing with traditional inorganic solar cells (e.g. monocrystalline silicon based solar cell), organic solar cells (OSCs) exhibit unique advantages such as low cost, light weight, flexibility and convenient large-area printing, along with the high batch-to-batch performance consistency of small molecule photovoltaic materials, which promotes the rapid development of small molecule OSCs in last five years. As one of the most important components of OSCs, the donor materials play a decisive role in determining the performance of corresponding photovoltaic devices. Several series of promising small molecule donor materials with high performance have been reviewed systematically. The characteristics and trends of these materials in molecular design, device construction and morphology control are summarized through the analysis of relevant research progress. Moreover, the main challenges and problems in the current research field of organic small molecule photovoltaic materials are summarized, and prospects for the future development of related fields are put forward.
