Band Alignment and Composition of the Buried TiO2/GaInP Interface

Advanced Materials Interfaces, EarlyView.
Buried TiO2$\text{TiO}_2$/GaInP interfaces formed by mild plasma‐enhanced ALD are shown to be largely insensitive to the initial GaInP surface condition. Angle‐dependent photoelectron spectroscopy reveals similar interfacial chemistry and band alignment for phosphorus‐rich and naturally oxidized surfaces, demonstrating a robust pathway for reproducible

Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes

Advanced Optical Materials, EarlyView.
Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.
