چکیده
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.

CHARACTERIZATION OF ELECTROSPUN BaTiO3/POLYVINYLPYRROLIDON E(PVP) NANOFIBERS
Barium titanate (BaTiO3, BTO) ferroelectrics are polar material that exhibits net spontaneous polarization without external applied field [1,2]. The polarization can be reoriented by applying the electric field. BTO with perovskite structure is widely used due to their ferroelectric, pyroelectric and piezoelectric properties in various electronic applications such as multi-layer ceramic capacit...
متن کاملElectrospun Nitrocellulose and Composite Nanofibers
Electrospinning was applied to nitrocellulose (NC) solutions in DMF, DMSO and Ethyl methyl keton to obtain NC nanofibers. Electrospraying process was observed when DMF was used as solvent. In comparison to NC/DMF, NC/DMSO solution resulted in the formation of a coating film as indicate by SEM. Two different electrospun nanofibers, smooth nanofibers wit...
