Electrochemical Design of Atomically Conformal Ga2O3 Buffer Layers via Cu2O‐Catalyzed Nitrate Reduction Reaction for Efficient Cu2O Photocathodes

Carbon Energy, EarlyView.
Cu2O catalyzes nitrate reduction to locally generate OH− at the electrode surface, enabling the first uniform electrochemical deposition of Ga2O3. The Cu2O/Ga2O3‐based photocathodes achieve onset potentials above 1 VRHE, 3.8% solar‐to‐hydrogen efficiency, and stable operation for over 60 h in all‐inorganic tandem PEC devices.

1D/3D Heterojunction for High‐Efficiency Hole‐Transport Layer‐Free Carbon‐Based Wide‐Bandgap Perovskite Solar Cells

Carbon Energy, EarlyView.
By modifying wide‐bandgap high‐Cs perovskite surfaces with quaternary ammonium salts of varying alkyl‐chain lengths, tetrapropylammonium bromide (TPABr) is shown to successfully construct a 1D/3D heterojunction. This structure effectively passivates interface defects and optimizes energy level alignment, achieving a champion efficiency of 20.14% with ...
