Research progress of organic solar cells based on polymerized small-molecule acceptors
All-polymer solar cells(all-PSCs)are a kind of organic solar cells(OSCs),which have attracted significant attention due to their distinctive advantages,including excellent morphological stability and mechanical stretchability.In recent years,the limitations of fullerene acceptors and their derivatives constrain the further advancement of photovoltaic performance.n-Type polymer electron acceptors have been developed because of their advantages including adjustable energy level,high absorption coefficient,excellent electrical and photoelectric properties.Thanks to the rapid development of n-type polymerized small molecule acceptors(PSMAs),the power conversion efficiencies(PCEs)of all-PSCs has been significantly improved in several years.In this review article,the development of PSMAs and the research progress of all-PSCs were summarized and the future development direction of OSCs was also prospected.
