The ternary strategy is one of the effective methods to regulate the morphology of the active layer in organic solar cells (OSCs). In this work, the ternary OSCs with bulk heterojunction (BHJ) or layer‐by‐layer (LbL) active layers are prepared by using the polymer donor PM6 and the non‐fullerene acceptor L8‐BO as the main system and the fullerene acceptor PC71BM as the third component. The power conversion...
A series of binary and ternary polymer solar cells (PSCs) is successfully fabricated. The optimal ternary PSCs achieve a power conversion efficiency (PCE) of 18.14%, benefiting from the increased short circuit current density (JSC) of 26.53 mA cm−2 and fill factor (FF) of 78.51% in comparison with the JSCs (25.05 mA cm−2 and 25.65 mA cm−2) and the FFs (77.13% and 76.55%) of the corresponding binary...
Efficient organic solar cells (OSCs) are fabricated using polymer PM6 as donor, and IPTBO‐4Cl and MF1 as acceptors. The power conversion efficiency (PCE) of IPTBO‐4Cl based and MF1 based binary OSCs individually arrive to 14.94% and 12.07%, exhibiting markedly different short circuit current density (JSC) of 23.18 mA cm−2 versus 17.01 mA cm−2, fill factor (FF) of 72.17% versus 78.18% and similar open...
