Advancement in Tandem Solar Cell Technology

-Indian researchers propose tandem solar cells with a CIGS top cell and a bottom cell based on single-walled carbon nanotubes (SWCNTs).

-The tandem cell design includes an ultra-thin WSeTe buffer layer in the top cell and a zirconium disulfide (ZrS2) buffer layer in the bottom cell.

-SWCNTs offer flexibility and stability, ideal for large surface areas.

-The CIGS top cell and SWCNT bottom cell achieve individual efficiencies of 23.69% and 17.10%, respectively, with a combined efficiency of 38.91% for the tandem cell.

-This innovation could revolutionize solar energy generation
