An organic solar cell comprises a photoactive layer that comprises at least one donor polymer and two non-fullerene molecular acceptors. Further, an organic solar cell comprises a photoactive layer that comprises one donor polymer, one fullerene acceptor, and one non-fullerene molecular acceptor. The donor polymer may exhibit temperature dependent aggregation (TDA) properties in solution, wherein the absorption onset of the polymer solution exhibits a red shift of at least 80 nm when the solution is cooled from 100° C. to room temperature or the absorption onset of the polymer solution exhibits a red shift of at least 40 nm when the solution is cooled from 100° C. to 0° C.
