Abstract

Solar energy is one of the most promising renewable energy alternatives for the replacement of traditional fossil fuels. CdTe photovoltaics (PVs) are thin-film solar cells that have the highest market share among all thin-film technologies. Previous LCA studies of CdTe PVs were based on the data from countries that have similar level of industrialization and strict environmental policies. Thus, to date, no LCA results have explored impacts of dramatic geographic diversity on environmental performance of CdTe PVs. Furthermore, ...
