Photovoltaic Effect in a III‐IV‐V Compound Semiconductor
Progress 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.

Beyond the Gold Standard: Towards Industrially Viable Electrodes for Durable Perovskite Solar Cells
Advanced Energy Materials, Volume 16, Issue 34, 9 September 2026.Transparent and opaque electrode materials are mapped by raw material cost per 1 m2 electrode area and retained median device efficiency after heat–light ageing. FTO offers a lower‐cost and more stable alternative to ITO, while Cr/Al provides the lowest‐cost rear electrode investigated with Au‐like stability and substantially improved durability ...

Recent Development in Solar‐to‐Hydrogen Conversion Systems
WIREs Energy and Environment, Volume 15, Issue 3, September 2026.This review compares three solar‐driven hydrogen production methods, photocatalysis (PC), photoelectrochemical cells (PEC), and photovoltaic–electrochemical (PV–EC) systems by examining their mechanisms, materials, stability, and efficiency. Nanocrystal‐based PC catalysts achieved the highest quantum efficiency (94%), while PV–EC and Si nanowire PEC ...

Band Alignment and Composition of the Buried TiO2/GaInP Interface
Advanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.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
