The Walmart projects will use copper indium gallium diselenide (CIGS) and cadmium telluride(CdTe) thin-film modules. The company says its large-scale on-siteinstallation of CIGS could help further the development of thistechnology and bring it to market faster, while its use of CdTe couldhelp make the case for other businesses to adopt the technology foron-site commercial use.
