Double-absorber thin-film solar cell with 34% efficiency
Double-absorber thin-film solar cell with 34% efficiency
Power-conversion efficiency is a critical factor for the wider adoption of solar-cell modules. Thin-film solar cells are cheap and easy to manufacture, but their efficiencies are low compared to crystalline-silicon solar cells and need to be improved. A thin-film solar cell with two absorber layers (instead of only one), with …
