Obtaining Nanofibers Based on Perovskite-Polymer Composites for Applying in Solar Cells

Influence of Electrospinning Setup Parameters on Properties of Polymer-Perovskite Nanofibers

“…Electrospun nanofibers have attracted a lot of attention in scientific and industrial communities due to their unique properties, such as light weight, flexibility, controllable properties, and low cost, which have allowed them to be widely applied in many fields, e.g., energy generation and storage, sensors, drug delivery, filtration, etc. [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. The type of material (i.e., polymers and/or additives) and its properties (optical, electrical, mechanical, etc.)…”

“…The type of material (i.e., polymers and/or additives) and its properties (optical, electrical, mechanical, etc.) determine their application area [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. The properties of nanofibers can be optimized by manipulating their thickness, diameter, and orientation of nanofibers (their structure) [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”

“…Beads and drops lead to inhomogeneous properties of nanofibers and could result in a strong drop in their properties [ 17 , 18 , 19 ]. The structure of nanofibers can be controlled by various parameters related to the electrospinning setup (e.g., an electrical voltage, a working distance, a feed rate, a needle diameter, and a collector type), the electrospinning solution, and the surrounding environment [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Thus, controlling electrospinning parameters is crucial for the optimal utilization of nanofibers.…”

“…Thus, controlling electrospinning parameters is crucial for the optimal utilization of nanofibers. Recently, polymer-perovskite nanofibers have emerged as promising materials to fabricate flexible and extensible perovskite optoelectronic devices [ 8 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. One-stage [ 8 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ], two-stage [ 27 , 28 ], or core-shell [ 8 , 29 , 30 , 31 ] electrospinning processes have been commonly used to prepare this type of nanofibers.…”
