Exploring Ternary Organic Solar Cells for the Improved Efficiency of 16.5% with the Compatible Nonacyclic Carbazole-Based Nonfullerene Acceptors as the Third Component

In this study, two dithieno[3,2-b]thiophenecyclopentacarbazole (DTTC)-based nonfullerene acceptors (NFAs) named DTTC-4F-C8 and DTTC-4Cl-C9 are designed, synthesized, and incorporated as the second ...
