Photoelectrochemical (PEC) solar-fuel conversion is a promising approach to converting
energy from sunlight into storable chemical fuels. The development of low cost, highly …

Solar cells rely on the efficient generation of electrons and holes and the subsequent
collection of these photoexcited charge carriers at spatially separated electrodes. High wafer …

A degenerate p-type conduction of cuprous iodide (CuI) thin films is achieved at the iodine-
rich growth condition, allowing for the record high room-temperature conductivity of∼ 156 …

We report on the fabrication of heterojunction solar cells made by deposition of transparent
conducting oxide (TCO) films on Cu 2 O substrates. The TCO films have been grown by ion …

This study revisits the issue of rare earth cation substitutions into barium titanate. Analysis
based upon crystal chemistry, defect chemistry and metastable states is presented to aid …

This study revealed the nature of native defects and their roles in ZnO through positron
annihilation and optical transmission measurements. It showed oxygen vacancies are the …

This paper reviews the recent developments in first-principles total energy studies of the
phenomenological equilibrium'doping limit rule'that governs the maximum electrical …

Mixed ionic–electronic conductors (MIECs) are examined first with respect to their possible
applications and then with respect to their properties. The emphasis is on electrochemical …

This work aims at reviewing the most impactful results obtained on the development of Cu-
based photocathodes. The need of a sustainable exploitation of renewable energy sources …

Abstract Electrodeposited Cu2O‐ZnO heterojunctions are promising low‐cost solar cells.
While nanostructured architectures improve charge collection in these devices, low open …
