Molecular-ink route to 13.0% efficient low-bandgap CuIn(S,Se)2 and 14.7% efficient Cu(In,Ga)(S,Se)2 solar cells
(Energy and Environmental Science, Royal Society of Chemistry, 2015-12-07)
Solar cells based on Cu(In,Ga)(S,Se)2 absorber layers have achieved the highest conversion efficiency amongst several thin film solar technologies but have so far struggled to translate their high performance into cost advantages on a module level. The use of printing processes has the potential to close that gap, provided ...
