摘要: A new organometallic halide perovskite (OHP) synthesis method, whereby a polymer melt is used to thermodynamically drive the reaction that forms OHP crystallites, demonstrated. The method allows for facile encapsulation of moisture-sensitive without loss simplicity during fabrication, which makes materials so attractive photovoltaic industry. Degradation crystallites embedded in polystyrene matrix was studied using UV-Vis absorbance over period several days. degrade as result reversible nature crystallites. After reversion precursors (PbI 2 and CH 3 NH I) I irreversibly degrades [2] allowing degradation be tracked via optical interrogation. Additionally, surface morphology elemental analysis fabricated samples carried out SEM/EDS techniques.
