Abstract

Abstract : In article number 2001476, Xugang Guo and co‐workers develop two ultranarrow‐bandgap n‐type polymer semiconductors, which enable efficient electron transport in organic thin‐film transistors with a highest electron mobility of 1.72 cm 2 V −1 s −1 and which deliver remarkable photovoltaic performance with a highest power conversion efficiency of 10.22% and short‐circuit current up to 22.52 mA cm −2 . The emergence of such polymers will guide materials innovation for realizing highperformance fully flexible all‐polymer solar cell modules.
