Abstract
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 deposited CIGS film using peeling‐off powders was similar. A secondary phase is not generated on the surface of the deposited CIGS film by SEM observation. From these results, we thought that the CIGS materials from solar cell structures were able to be recycled for new solar cell absorber layer. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
