A numerical model have been developed in order to describe and achieve deeper understanding of experimentally obtained I-V curves from Cu2O/ZnO p-n heterojunctions for potential use as future solar cell material. The model was created using the simulation software COMSOL Multiphysics® and their semiconductor module. To experimentally study the samples two approaches were taken: (1) macro-electrical measurements and (2) local I-V measurements using conductive AFM.

The dense and curl-shaped copper oxide nanowires were carried out through thermal transformation of one-dimensional Cu(OH)2. And then, we propose a high stable and efficient Cu2O/ZnO photocathode for photoelectrochemical water splitting. Their morphology, structure and composition were examined with SEM, TEM, XRD, XPS and Raman , respectively. For PEC char

First, ITO films were fabricated of by RF magnetron sputtering and post-preparation annealing at high-temperature in order to improve the conductivity of ITO films. Secondary, Cu2O films were grown by RF magnetron sputtering, in which Cu was used as the sputtering target. The RF power and the O2 flow rate was changed in order to obtain a cuprous oxide film with different characteristics. Finally, ZnO films were grown by RF magnetron sputtering, in which ZnO was used

Transmission electron microscopy (TEM) and X-ray reflectivity (XRR) were used to observe the structural properties, the deposition and the diffusion of superlattices.
