文摘

CH₃NH₃PbI₃ perovskite nanofibers were synthesized by versatile electrospinning techniques. The synthetic CH₃NH₃PbI₃ nanofibers were characterized by X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, and photoluminescence. As counter electrodes, the synthesized nanofibers increased the performance of the dye-sensitized solar cells from 1.58 to 2.09%. This improvement was attributed to the enhanced smoothness and efficiency of the electron transport path. Thus, CH₃NH₃PbI₃ perovskites nanofibers are potential alternative to platinum counter electrodes in dye-sensitized solar cells.
