Improving the efficiency of tandem solar cells

https://techxplore.com/news/2022-04-efficiency-tandem-solar-cells.html

"efficiency of 29.2%... combining perovskite cell with a textured silicon cell... yields will likely top out at around 27% in the foreseeable future, owing to fundamental thermodynamic limitations. Modules incorporating these solar cells will have maximum yields of around 23–25%... limitations can be overcome by combining silicon with solar cell that absorbs blue-green part of solar spectrum and more efficiently, forming what's called tandem"
