Abstract:
Three BTA-based polymers J52-F, PE3 and PE3-FCl, are utilized to investigate the effects of molecular configuration change and asymmetric halogen substitution on the device performance of all-PSCs. Ultimately, the binary all-PSCs based on PE3-FCl:PY-IT achieve a record power conversion efficiency (PCE) of 17.73%, which is among the highest values for all-PSCs containing BTA-based polymers.
