Photovoltaic Effect in a III‐IV‐V Compound Semiconductor

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

Silver‐Modulated Copper Dynamics Under Pulsed Tandem Electrochemical CO2 Reduction

open access: yesSmall, EarlyView.
Under pulsed CO2 reduction, Ag does more than provide CO for tandem catalysis. It redirects how Cu dissolves, redeposits, and remains catalytically relevant, generating an Ag‐rich yet Cu‐active working state. Correlative surface and solution analysis reveal that tandem performance emerges from dynamic material redistribution rather than from a static ...
