CIGS cell with ultra-thin glass substrate hits record efficiency of
Scientists at the Korea Institute of Energy Research (KIER) have developed a CIGS solar cell with ultra-thin glass (UTG), an emerging substrate known for its exceptional
However, flexible ultra-thin glass (UTG) substrate, an emerging material used in the display and touch panel industry, holds immense promise for the future of photovoltaics. UTG offers distinct advantages, making it a more suitable candidate for high-efficiency CIGSe solar cells.
Demonstrated flexible, Cd‐free Cu (In,Ga)Se₂ solar cells on emerging ultrathin glass substrates. Achieved a record efficiency of 17.81 % for flexible, Cd‐free Cu (In,Ga)Se₂ solar cells on ultrathin glass substrates. Achieved an efficiency of 10.11 % for 60 cm² large-area Cd-free CIGSe cells.
The new cell concept was introduced in the study “ High-efficiency cadmium-free Cu (In,Ga)Se 2 flexible thin-film solar cells on ultra-thin glass as an emerging substrate,” published in the Journal of Alloys and Compounds.
Cu (In,Ga)Se 2 (CIGSe) solar cells have significantly progressed in associated flexible photovoltaic technologies. Recently, ultra-thin glass (UTG) has been recognized as an emerging novel flexible substrate that is compatible with conventional thick glass-based methodology.
