The improved crystallinity and reduced defect density, along with the formation of a Schottky junction between the MXene nanosheets and CsPbI2Br, enhance the separation and transfer of the photogenerated electron-hole pairs, leading to a significantly increased power conversion efficiency. Additionally, the MXene-added CsPbI2Br layers exhibit improved humidity resistance.

Summary: The study investigates the effects of mixed passivation on all-inorganic perovskite (CsPbI2Br) solar cells for the first time, resulting in improved film quality and energy level alignment. The passivation enhances hole extraction, drives interface electron separation, suppresses charge recombination, and achieves a high open-circuit voltage and fill factor in the devices. Moreover, the treated devices exhibit remarkable long-term stability with minimal efficiency loss after storage in a glove box for over 1000 hours without encapsulation.

Summary: The presence of defects on the surface of CsPbI2Br perovskite films can lead to inferior power conversion efficiency of solar cells. By coating phenylethylammonium iodide (PEAI) solution onto the surface and annealing, the defect density on the surface can be effectively reduced. In situ characterization shows that the PEAI treatment induces surface crystal reconstruction and decreases trap density, leading to a high power conversion efficiency of 13.38% for the CsPbI2Br perovskite solar cell with a carbon electrode.

Summary: Organic semiconductors are crucial in thin-film electronic devices, especially as hole transport layers (HTLs) in perovskite solar cells (PSCs). Spiro-OMeTAD and PTAA have been the leading materials for high efficiency HTLs, with research on their properties contributing to a better understanding of their success mechanisms. This review provides key insights into the electronic and morphological properties, doping strategies, and degradation pathways of spiro-OMeTAD and PTAA, guiding the development of future HTL materials with improved stability and efficiency for PSCs.

Summary: Lead halide perovskite has great potential for solar energy applications, but the toxic nature of lead hinders its widespread use. Tin (Sn2+) has been suggested as a replacement for lead to reduce toxicity, but defects in Sn2+ halide perovskites result in poor performance. The focus of research is on device engineering to enhance the efficiency and stability of Sn2+ and mixed Pb2+/Sn2+ based perovskite solar cells.
