2013年10月23日 · A hydrothermal approach is developed to fabricate Cu 2 O film via in situ redox reaction between Cu 2+ and Cu plate. The crystallization process under different conditions was demonstrated, and the crystal structure of Cu 2 O was verified by XRD, Raman and XPS characterizations.

2013年11月30日 · Cu2O films deposited from basic solutions using lactate or citrate ligands contain more impurities than films deposited from acidic lactate or acetate solutions. Depth profiling reveals that sodium is located as deep as 100 nm below the surface of one film in the form of Na O Cu bonds.

2025年1月16日 · The epitaxial growth of the Cu2O homojunction with n/p films of the same crystal orientation reduces the interface states and the formation of a textured structure on the surface helps the photons to be absorbed more effectively, which both enhance the photovoltaic conversion efficiency of Cu2O film solar cells.

2020年2月3日 · In this work, highly Cu 2 O film purity have been synthesized via electrodeposition technique by means of a variable applied potential [cyclic voltammetry (CV), linear sweep voltammetry (LSV) and − 0.5 V]. This paper highlights the effect of using variable potential approaches during the film preparation on the properties of Cu 2 O-deposited films.

2023年9月15日 · Cu 2 O can be n-type and p-type depending on the oxygen and copper vacancies as either photocathode or photoanode for water splitting. However, the synthesis of n-type Cu 2 O is still a challenge. At the condition of pH= 6 and ΔU= −0.05 V, n-type Cu 2 O films can be electrodeposited at varied temperatures.
