Comparison of device performance and measured transport parameters in widely‐varying Cu(In,Ga) (Se,S) solar cells
We report the results of an extensive study employing numerous methods to characterize carrier transport within copper indium gallium sulfoselenide (CIGSS) photovoltaic devices, whose absorber layers
Thermal Conductivity Reduction in CoSb3–CeO2 Nanocomposites
CoSb3 + x% CeO2 nanocomposites (x = 1, 3, 5) were synthesized by ball-milling and spark plasma sintering. Scanning electron microscopy showed that some CeO2 nano-inclusions sit at the boundaries of
Electronic Structure, Optical Properties, and Photoelectrochemical Activity of Sn-Doped Fe2O3 Thin Films
Hematite (Fe2O3) is a well-known oxide semiconductor suitable for photoelectrochemical (PEC) water splitting and industry gas sensing. It is widely known that Sn doping of Fe2O3 can enhance the dev...
Diversity of electronic transitions and photoluminescence properties of p-type cuprous oxide films: A temperature-dependent spectral transmittance study
Cuprous oxide films have been deposited on quartz substrates by a sol-gel method under various annealing temperatures. The X-ray diffraction analysis and Raman scattering show that all the films are
High-efficiency perovskite solar cells improved with low-cost orthorhombic Cu2ZnSnS4 as the hole-transporting layer
Quaternary copper chalcogenide Cu2ZnSnS4 (CZTS) nanoparticles (NPs) were synthesized with the sol-gel technique and used as the hole-transporting layer (HTL), achieving a power-conversion efficiency
Electronic structure andp-type conduction mechanism of spinel cobaltite oxide thin films
This work reports a fundamental study on the electronic structure, optical properties, and defect chemistry of a series of Co-based spinel oxide ( Co 3 O 4 , ZnCo 2 O 4 , and CoAl 2 O 4 ) epitaxial
