Thermal evaporated PbI2 enables high-quality perovskite films and improves their solar cell performance
Munkhtuul Gantumur et al 2024 Jpn. J. Appl. Phys. 63 015501
The study in "Japanese Journal of Applied Physics" by Munkhtuul Gantumur et al. explores the use of vacuum-deposited PbI2 to enhance the quality of perovskite films in solar cells. This method significantly improves the film's quality compared to spin-coated PbI2, leading to higher power conversion efficiency and better thermal stability in perovskite solar cells. Vacuum-deposited PbI2 results in uniform, pinhole-free films, facilitating efficient intercalation of MAI and the formation of high-quality MAPbI3 perovskite layers. This method also reduces ion migration, contributing to the improved performance and stability of the solar cells.
How Paios was used
Paios was used for electrochemical impedance spectroscopy (EIS) to examine the perovskite solar cells (PSCs). This technique provided insights into the electrical properties of the cells, such as resistance and capacitance, which are crucial for understanding and improving their performance.
