CsI Enhanced Buried Interface for Efficient and UV-Robust Perovskite Solar Cells

Hang Xu et al.

Summary: By utilizing CsI-SnO2 complex as the buried interface for the electron transport layer, an effective strategy for enhancing the efficiency and stability of perovskite solar cells has been achieved. CsI modification facilitates perovskite film growth and defect passivation, while the gradient distribution of Cs+ contributes to suitable band alignment and enhanced resistance to UV exposure, resulting in significantly improved power conversion efficiency and UV stability for FAPbI(3)-based PSCs.

Understanding Instability in Formamidinium Lead Halide Perovskites: Kinetics of Transformative Reactions at Grain and Subgrain Boundaries

Parth Raval et al.

Summary: This study investigates the moisture-induced transformative reactions in formamidinium-based perovskites and shows that the ambient stability of these materials can be adjusted by various factors. The effects of water vapor, particle size, and light illumination on the kinetic pathways of the phase transformation are analyzed, and the different kinetics of the transformation at grain and subgrain boundaries are studied. Insights into the structures and dynamics of the trapped phases are obtained using solid-state NMR spectroscopy.

Light-induced reversal of ion segregation in mixed-halide perovskites

Wenxin Mao et al.

Summary: By controlling the intensity of light irradiation, the segregation and remixing of halide ions in mixed-halide perovskites can be achieved, allowing for the control of their chemical composition and optical bandgap. This opens up new opportunities for the use of mixed-halide perovskites in concentrator and tandem solar cells, high-power light-emissive devices, and optical memory applications.

Perovskite solar cells with atomically coherent interlayers on SnO2 electrodes

Hanul Min et al.

Summary: By introducing an interlayer between the electron-transporting and perovskite layers in perovskite solar cells, researchers have successfully enhanced charge extraction and transport from the perovskite, leading to higher power conversion efficiency and fewer interfacial defects. The coherent interlayer allowed the fabrication of devices with a certified efficiency of 25.5%, which maintained about 90% of its initial efficiency even after continuous light exposure for 500 hours. The findings provide guidelines for designing defect-minimizing interfaces in metal halide perovskites and electron-transporting layers.

Grain Transformation and Degradation Mechanism of Formamidinium and Cesium Lead Iodide Perovskite under Humidity and Light

Kevin Ho et al.

Summary: Understanding the degradation pathways of mixed cation perovskites reveals that exposure to both light and high humidity can lead to a multistep decomposition process, involving phase separation and evaporation of certain components like FA. This knowledge can aid in the development of more stable perovskites by suppressing grain transformation during phase separation.

Interfacial toughening with self-assembled monolayers enhances perovskite solar cell reliability

Zhenghong Dai et al.

Summary: The use of iodine-terminated self-assembled monolayer (I-SAM) in perovskite solar cells (PSCs) leads to increased adhesion toughness at the interface, improved power conversion efficiency, reduced hysteresis, and enhanced operational stability. This is attributed to a decrease in hydroxyl groups at the interface and higher interfacial toughness achieved with I-SAM treatment.
