Abstract

This work is based on the use of organic inorganic hybrid perovskite as a light absorber in PSC. Organic inorganic hybrid perovskites as a light absorber is quite exciting because of the very drastic development happened in a short span of time. The scientific community welcomed perovskite as active material in the solar cells because of its ease of fabrication, flexibility, low cost and its ability to deliver high PCE. What makes perovskites, promising material for photovoltaics is its high intrinsic carrier mobilities, high molar extinction coefficients, long charge diffusion lengths, strong absorption over the entire visible spectrum. Compared with silicon solar cells, organic inorganic hybrid perovskite solar cells are 200 times thinner and are processed at low temperatures and ambient conditions which reduce their cost of production. They are better than their pure organic counter parts in terms of delivering high efficiencies. They have improved a lot in a short period and it is having the highest power to weight ratio among viable photovoltaic technologies. This work is mainly focusing on the role of solvent treatment on PEDOT:PSS, which is one of the widely used Hole transporting material in perovskite solar cells.
