Abstract

Abstract : Efficient homo‐tandem and triple‐junction polymer solar cells are constructed by stacking identical subcells composed of the wide‐bandgap polymer PBDTTPD, achieving power conversion efficiencies >8% paralleled by open‐circuit voltages >1.8 V. The high‐voltage homo‐tandem is used to demonstrate PV‐driven electrochemical water splitting with an estimated solar‐to‐hydrogen conversion efficiency of ≈6%.
