Achieving High Efficiency of PTB7-Based Polymer Solar Cells via Integrated Optimization of Both Anode and Cathode Interlayers

A poly(thieno[3,4‐b]‐thiophene/benzodi­thiophene) (PTB7)‐based polymer solar cell (PSC) with conventional structure can achieve a significant power conversion efficiency of 8.42%, which is realized by integrated optimization of both anode and cathode interlayers. The effects of a conjugated micropor...

Zusammenfassung:A poly(thieno[3,4‐b]‐thiophene/benzodi­thiophene) (PTB7)‐based polymer solar cell (PSC) with conventional structure can achieve a significant power conversion efficiency of 8.42%, which is realized by integrated optimization of both anode and cathode interlayers. The effects of a conjugated microporous polymer film as the anode interlayer are threefold: it enhances the contact with active layer, increases the work function and conductivity, and blocks electrons.
