Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...

High‐Mobility and Low Carrier Concentration Transparent Conducting Oxide Rear Contact for Bifacial CIGS Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study investigates high‐mobility, low carrier concentration (CC) transparent conducting oxides (TCOs) as back contacts in bifacial Cu (In, Ga)Se2 (CIGS) solar cells. These TCOs enhance rear‐side light absorption in CIGS and external quantum efficiency, improving overall performance by offering high transparency, low reflectance, and maintaining ...
