为了开发一种光无线电能传输系统，对溴基钙钛矿薄膜的光电性能进行了评估。在衬底预热后，采用反溶剂法制备了CH3NH3PbBr3（MAPbBr3）薄膜。低温激子发射和发射光谱中相变峰的不连续位移表明MAPbBr 3薄膜在TiO 2上具有高的光学质量。MAPbBr3薄膜的Urbach能量和扩散长度分别为22.7 meV和1.14 μm。薄膜在单色光下表现出良好的太阳能电池性能，效率超过20%。
The optoelectrical properties of bromide-based perovskite thin films were evaluated to develop an optical wireless power transmission system. CH3NH3PbBr3 (MAPbBr3) films were deposited by the anti-solvent method after substrate preheating. The low-temperature exciton emission and discontinuous peak shift from phase transitions in the emission spectra indicate the high optical quality of MAPbBr3 films on TiO2. The Urbach energy and diffusion length of the MAPbBr3 thin films on TiO2 were 22.7 meV and 1.14 μm, respectively. The films exhibited good solar cell performance under monochromatic light with an efficiency over 20%.
