Ultrathin high band gap solar cells with improved efficiencies from the world’s oldest photovoltaic material

Wide band gap semiconductors are important for the development of tandem photovoltaics. By introducing buffer layers at the front and rear side of solar cells based on selenium; Todorov et al., reduce interface recombination losses to achieve photoconversion efficiencies of 6.5%.
