Organic Solar Cells In article number 2000460 , Fernando Langa, Ganesh D. Sharma, and co‐workers construct a simple and efficient ternary organic solar cell based on two well‐defined conjugated small molecules donors FG3 and FG4, and Y6 as a well‐known nonfullerene small molecule acceptor. This results in best‐performance in comparison with the binary counter parts, showing an excellent power conversion efficiency of 14.31% with a high fill factor and short‐circuit current density.
