   Hace 1 día · Perovskite solar cells are often tested indoors under conditions that do not represent outdoor use. Fei et al. found that faster degradation of the cells in outdoor testing stems from higher ultraviolet levels that cause debonding at the indium-tin oxide and hybrid hole-transporter layer interfaces.The authors designed a hole-transfer material with a phosphonic acid group bonding to indium-tin ...

   Hace 3 días · Developing high-performance polarization-sensitive ultraviolet photodetectors is crucial for their application in military remote sensing, detection, bio-inspired navigation, and machine vision. However, the significant absorption in the visible light range severely limits the application of polarization-sensitive ultraviolet photodetectors, such as high-quality anti-interference imaging.
