Solution Processed Transparent Tio2 Moo3 Heterojunction for Energy Conversion and Storage Applications

Abstract

Energy demand is everlasting due to the increase in population growth. Developing technology to efficiently harness, save and store electrical energy is the much need solution for the same. As the energy consumption in commercial and residential buildings is almost 41% of the total consumption, the integration of energy saving transparent devices would be one of the significant ways to efficiently meet the energy crisis in smart buildings. Thus, the transparent devices for energy conversion and storage are considered as the heart of future smart technologies. This thesis work presents the explorations on the energy harnessing, saving and storing applications of cost-effective, non-toxic and transparent multifunctional TiO2/MoO3 bilayer heterojunction thin film material. TiO2/MoO3 heterojunction film was chosen for the study due to the properties of TiO2 and MoO3 suitable for wide applications of the materials and the significance of type II heterojunction. The fabricated heterojunction was investigated for the self-powered UV photodetectors, electrochromic devices and photo driven as well as electrochromic supercapacitors. The thesis is divided into six chapters with the first chapter providing the introduction to the thesis topic and literature survey of TiO2/MoO3 heterojunction newline
