Synthesis and Microstructural Characterization of Nano Lead Perovskite Compounds for Solar Cell

Abstract

In the past few years, metal-halide perovskites have attracted significant attention from the photovoltaic community which leads their efficiencies to rapidly climbed from 3.8% to 23.7%. This evolution has been extraordinary and unprecedented in solar cells history and can be ascribed to the outstanding properties of the perovskite materials. Free-hole perovskite solar cell without precious metals electrode are the chief toward large scale and low cost production of perovskite solar cells, and thus commercialization. In this study, TiO2/CH3NH3PbI3/C devices were fabricated in air, via two step dipping method, using carbon as a counter electrode with the aid of the facile doctor blade technique, which simplifies the processing and lowers the threshold of fabrication process. The research work presented in this thesis consists of three main parts:
