Study of the Al-grading effect in the crystallisation of chalcopyrite Cu(In,Al)Se2 thin films selenised at different temperatures [PDF]

, 2013
Chalcopyrite CuIn1−xAlxSe2 (CIAS) thin films with an atomic ratio of Al/(In + Al) = 0.4 were grown by a two-stage process onto soda-lime glass substrates.

Inverted Metamorphic III–V Triple-Junction Solar Cell with a 1 eV CuInSe2 Bottom Subcell

International Journal of Photoenergy, 2014
A new triple-junction solar cell (3J) design exploiting the highly absorptive I–III–VI chalcopyrite CuInSe2 material is proposed as an alternative to III–V semiconductor 3J solar cells. The proposed structure consists of GaInP (1.9 eV)/Ga(In)As (1.4 eV)/

Anion vacancies as a source of persistent photoconductivity in II-VI and chalcopyrite semiconductors

, 2005
Using first-principles electronic structure calculations we identify the anion vacancies in II-VI and chalcopyrite Cu-III-VI2 semiconductors as a class of intrinsic defects that can exhibit metastable behavior.

Engineering Asymmetry: How Chirality Boosts Catalysis, Spin Selectivity, and Light–Matter Interactions

ChemPhotoChem, Volume 10, Issue 4, April 2026.
This review connects chiroptical spectroscopy, asymmetric catalysis, and spintronics, revealing how chirality influences the interactions of matter with light, charge, and spin. Across diverse systems, remarkable chiroptical effects emerge, showing among others that high efficiencies can arise without absolute enantiopurity, and that functionality is ...

MAPbI3-on-CuInSe2 two-terminal monolithically integrated and four-terminal mechanically stacked tandem solar cells: A Theoretical Investigation Using SCAPS-1D

Results in Optics, 2023
Two-terminal (2-T) and four-terminal (4-T) tandem solar cells with wide bandgap perovskite (MAPbI3) as the top sub-cell and low bandgap copper indium diselenide (CuInSe2, CIS) as the bottom sub-cell have potential to outperform the single-junction power ...

Influence of an Sb doping layer in CIGS thin-film solar cells: a photoluminescence study [PDF]

, 2013
Sb doping of Cu(In,Ga)Se2 (CIGS) solar cells has been reported to exhibit a positive effect on the morphology of the absorber layer, offering a possibility to lower manufacturing cost by lowering the annealing temperatures during the CIGS deposition.

Recent Progress in Cu2Se‐Based Thermoelectric Materials

cMat, Volume 3, Issue 1, March 2026.
ABSTRACT Thermoelectric technology enables direct conversion between heat and electricity, offering great promise for waste heat recovery and electronic cooling. Due to non‐toxicity, earth‐abundant elements, a wide service temperature range, and high thermoelectric performance, Cu2Se‐based thermoelectric materials have garnered significant attention ...

Morphological, Structural, and Optical Properties of Single-Phase Cu(In,Ga)Se2 Thin Films from the Selenization of Thermally Evaporated InSe/Cu/GaSe Precursors

Advances in Materials Science and Engineering, 2014
The relatively small band gap values (~1 eV) of CuInSe2 thin films limit the conversion efficiencies of completed CuInSe2/CdS/ZnO solar cell devices.

Chemical instability at chalcogenide surfaces impacts chalcopyrite devices well beyond the surface

Nature Communications, 2020
Anion vacancies are a hurdle for technologies based on chalcogenide semiconductors and topological insulators. Even at room temperature, oxidation and cyanide etching can lead to selenium vacancies in CuInSe2 photovoltaic material but suitable post ...
