Solar cells that make use of wasted light

        June 24, 2021 Nature | Cambridge | renewables: solar

Standard silicon solar cells convert a small fraction of incident light into electricity. An organic polymer film and quantum dot setup can convert wasted higher-energy photons (blue and green) via "singlet exciton fission" in a tandem construction to increase overall panel efficiency by 50% to about 35% (above the SQ limit).
