Hybrid perovskite solar cells are rapidly climbing in efficiency and are close to large-scale commercialization due to continued efforts in improving the opto-electronic properties and stability of hybrid perovskite materials. Improvements to the charge transport structures in hybrid perovskite solar cells allow for much higher charge extraction from perovskite solar cells, improving overall efficiency of solar cells utilizing electrospun charge transport structures. Electrospinning and post-processing techniques were utilized to produce high surface area electron and hole transport structures for use in perovskite solar cells, and opto-electronic properties and surface/ layer interactions were studied.
