Summary: In this study, the structures of amorphous boron carbide (a-BxC) were characterized using electron diffraction technology. It was found that the most favorable cluster in B4C generated by ion irradiation is a pentagonal pyramid, while C-C homonuclear bonds were formed in the deposited a-BxC thin film. X-ray photoemission spectroscopy revealed that the a-BxC thin film contains more carbon than B4C, leading to the formation of the homonuclear bonds.

Summary: Modification of charge transport layers is an effective method to enhance the performance of perovskite solar cells. The use of low-cost, water-soluble nonionic polymer polyacrylamide (PAM) to modify SnO2 improves the uniformity, wettability, and electron mobility of the film. This modification reduces defects in the perovskite film, increases the grain size, and improves energy-level alignment, leading to improved electron transfer. The power conversion efficiency of the modified SnO2-based PSCs is enhanced to 22.59%, and the devices retain 90% of their initial value after more than 1000 hours of storage under 50% relative humidity.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
