  • Thin-film photovoltaic devices are often based on toxic or rare materials. Here, Wang et al. grow oriented Sb2Se3 thin film on a ZnO buffer layer, and fabricate solar cells with a certified 5.9% conversion efficiency and which pass harsh stability tests under humidity, heat and illumination.

  • Bandgap gradient is a promising approach to improve the open-circuit voltage in thin film solar cells. Here, authors incorporate a Cd(O,S,Se,Te) region to realize the bandgap gradient at front interface and demonstrate Cd(Se,Te) solar cells with reduced recombination and a champion efficiency of 20.03%.
