Future fossil fuel scarcity and environmental degradation have demonstrated the need for renewable, low-carbon sources of energy to power an increasingly industrialized world. Solar energy, with its extraordinary resource base, is one of the most feasible long-term options for satisfying energy demand with minimal environmental impact. However, solar photovoltaic panels remain expensive and emp...

Biominerals are organic–inorganic nanocomposites exhibiting remarkable properties due to their unique configuration. Using optical spectroscopy and theoretical modeling, it is shown that the of a model bioinspired system, an inorganic semiconductor host (Cu2O) grown in presence amino acids (AAs), strongly influenced by latter. The absorption photoluminescence excitation spectra Cu2O-AAs blue-sh...

Cuprous oxide (Cu2O), a far-reaching photon-absorption layer, is active in the field of solar cells and sensors. In this work, Cu2O films prepared at low temperature by radio frequency (RF) magnetron sputtering holds branch-like crystalline morphology, optical transmittance unsatisfactory carrier mobility. However, peroxidation will occur when thermal excessive. By optimizing, (111)-oriented mo...

Cu fine-particle paste is a promising material to form low-cost interconnect for flexible electronics devices. It has been reported that particles can be sintered at low temperature (well below the half of melting point) through two-step heat treatment processes oxidation and reduction. However, mechanism sintering not clear yet. In this study, we investigated process fine by thermal gravimetri...

In this study, an EA-substituted tin based perovskite solar cell with different hole transport material (PEDOT: PSS, Cu2O, CuI, CZTSe) have been investigated using device simulation software. The effects of absorber thickness, defect density, operating temperature, J–V characteristics, and Quantum efficiency considered to enhance the performance cell. To confirm feasibility validate all results...

Muonium centres in Cu2O, Ag2O and CdO show hyperfine parameters spanning four orders of magnitude. They exemplify the three different categories of hydrogen defect centre in semiconducting and dielectric solids, with very different electronic structure and electrical activity, namely quasi-atomic (possibly deep acceptor), deep donor and shallow donor.
