High-efficiency CIGS solar cells with modified CIGS surface

Solar Energy Materials and Solar Cells, 2001
Abstract CIGS films were treated in In–S aqueous solution for high-efficiency CIGS solar cells. The In–S aqueous solution contained InCl 3 and CH 3 CSNH 2 (thioacetamide). The In–S treatment modified the CIGS surface favorably for high-efficiency CIGS solar cells as evidenced by the increase in V oc , J sc and FF.

Leaching and re-synthesis of CIGS nanocrystallites from spent CIGS targets

Advanced Powder Technology, 2016
Abstract The original target utilization is only about 30% in the CIGS (Cu(In, Ga)Se 2 ) thin film solar cell sputtering process. The remaining 70% of the target must be recycled to achieve sustainable use of the rare metals, In, Ga, and Se. It is therefore very important to establish spent CIGS target recycling technology to reduce environmental ...

Cu2S/CIGS core/shell nanowire arrays with epitaxial CIGS growth

Solar Energy Materials and Solar Cells, 2014
Abstract Cu2S/CuIn0.7Ga0.3Se2 (Cu2S/CIGS) core/shell nanowire arrays with epitaxial CIGS growth are synthesized by electrodepositing CIGS on Cu2S nanowire arrays. The electrodeposited CIGS is tetragonal CuIn0.7Ga0.3Se2 with a band gap of 1.310 eV. The crystal structure of Cu2S is similar to that of CIGS. The interplanar distance of Cu2S ( 2 ¯

CIGS absorbers and processes

Progress in Photovoltaics: Research and Applications, 2010
AbstractThe current status and future perspectives of Cu(In1−xGax)Se2(CIGS) solar cells and modules will be discussed in this paper. The conversion efficiencies of the state of the art laboratory‐scale CIGS solar cells exceeded 20%, which are comparable to those of crystalline Si solar cells.

Heterostructured CIGS–Au nanoparticles: from Au–CIGS side-by-side structure to Au-core/CIGS-shell configuration

Nanoscale, 2011
Heterostructured Au-Copper Indium Gallium Selenide (CIGS) nanoparticles (nps) with Au-CIGS side-by-side and Au-core/CIGS-shell configurations have been synthesized in a controllable manner using seed mediated growth. Detailed microstructure analysis reveals that (112) planes in the tetragonal chalcopyrite CIGS serve as the predominant termination ...

Recycling of CIGS absorber layer for deposition of CIGS film

physica status solidi c, 2013
AbstractWe tried to recycle CIGS thin film solar cell absorber layer as a deposition source. The deposition source is peeled off from Mo/SLG substrate. The recycled‐CIGS films were evaluated by XRD, Raman scattering spectroscopy, and SEM. As compared with high‐efficiency CIGS films, the XRD patterns and Raman spectra show that the crystallinity of ...

Surface modifications of CIGS absorbers and their effects on performances of CIGS solar cells

Ceramics International, 2021
Abstract The surface roughness of CIGS absorber and residual Cu–Se phase on the surface are two major factors greatly affecting the performance of CuInGaSe2 (CIGS) solar cells with the absorbers fabricated by the selenization annealing of Cu–In-Ga precursors. In this work, Br2–CH3OH solution is used to etch the surfaces of CIGS films to address these
