A small molecule DRCN5T as the donor with theE g optof 1.60 eV, and a 3D perylene diimide as electronic acceptor are used to fabricate non‐fullerene all‐small‐molecule solar cells. Upon thermal annealing, the efficiency of the device is enhanced from 0.47% to 6.16% with a high V oc of 1.04 V and a small energy loss of 0.56 eV.
