제목 High Energy Irradiation Treatment on Lead Iodide Precursor for Enhanced Perovskite Photovoltaics
초록 This research reveals the effects of exerting high energy radiation on the structure of lead iodide, (PbI2) precursor material used for organic-lead halide perovskite film. Specifically, the irradiation treatment affects the crystal structure and morphology of PbI2, thereby changes the perovskite precursors’ coordination chemistry when prepared in solution. Since the chemistry in the precursor solution largely affects the resultant perovskite thin film, irradiation treatment on PbI2 can be utilized to form perovskite with enhanced quality. According to our X-ray diffraction and optical analyses, irradiated PbI2 precursors have tendency to form high-valent iodoplumbates with organic solvents. Furthermore, optical and electrical analyses that proves increased power conversion efficiency of PSCs show that direct treatment on precursors with high energy sources can be an effective strategy for improving perovskite’s quality.
