Investigation of co-evaporated polycrystalline Cu(In,Ga)S2 thin film yielding 16.0 % efficiency solar cell

EPJ Photovoltaics, 2022
The interest for pure sulfide Cu(In,Ga)S2 chalcopyrite thin films is increasing again because their optical properties make them relevant candidates to be applied as top cell absorbers in tandem structures.

Prevalence and correlates of prior experimentation with e-cigarettes over conventional cigarettes among adolescents: Findings from the 2015 Korea Youth Risk Behaviour Web-based Survey

Tobacco Prevention and Cessation, 2019
Introduction As concern is increasing about electronic cigarette use among neversmoking youth, we aimed to examine the prevalence and correlates of prior experimentation of electronic cigarettes (e-cigs) over conventional cigarettes (c-cigs). Methods We

Triple junction solar cell with Cu In1-x Gex Se as absorbents layers

Revue des Énergies Renouvelables, 2023
The design of multi-junction solar cells is guided by both the theoretical optimum bandgap combinations as well as the realistic limitations to materials with these bandgaps. Nowadays, triple-junction III-V multi-junction solar cells are commonly used as

Sub‐1 ms Optoelectronic Synapse Based on {ZnCdO/ZnO} Multilayer Structure for High‐Speed Neuromorphic Vision Systems

Advanced Functional Materials, EarlyView.
Eu‐doped {ZnCdO/ZnO} structures grown on Si are developed, showcasing dual‐functionality controlled by europium doping. While high europium concentration transforms the device into an ultrafast, self‐powered photodetector, low‐doped structures can be used as an optoelectronic synapse.

How the absorber thickness influences the formation of reverse bias induced defects in CIGS solar cells

EPJ Photovoltaics, 2020
When a PV module is partially shaded, the shaded solar cells operate in a reverse bias condition. For Cu(In,Ga)Se2 cells this condition can cause defects that irreversibly reduce the output of these cells and the full module.

Influence of Substrate Temperature during In_xS_y Sputtering on Cu(In,Ga)Se₂/Buffer Interface Properties and Solar Cell Performance

Applied Sciences, 2020
Indium sulfide (InxSy)—besides CdS and Zn(O,S)—is already used as a buffer layer in chalcopyrite-type thin-film solar cells and modules. We discuss the influence of the substrate temperature during very fast magnetron sputtering of InxSy ...
