A Review on Preparation Techniques of Charge Transport Layer for Organic and Inorganic Perovskite Solar Cells

Abstract

The fascinating behavior of charge transport layer in organic and inorganic perovskite solar cells has piqued the interest of designers of semiconductor SnO2 nanoparticles (PSC). The goal of this research is to look at several techniques for manufacturing SnO2 films for use as charge transport layers in PSC. To comprehend the link between the attribute of nanostructured SnO2 films and the efficiency of solar cells, special attention is devoted to the production and properties of the SnO2 thin films. The spin-coating deposition of SnO2 nano fluids generated via surface modification of nano-colloids composed of SnO2 has been one of the key techniques for obtaining SnO2 layers. It has also been reported that preparing SnO2 nanoparticles using Tin (IV) salts results in a high-quality SnO2 film. Light-to-electricity conversion efficiency of about 25.5% has been claimed in many PSC papers [1]. One benefit of adopting SnO2 materials is that they have substantially greater conductivity than TiO2. This work also discusses the production of SnO2 nanoparticles, a different method of generating SnO2 charge transport materials that may be accomplished by the process of freeze-drying precursors known as Tin (IV). SnO2 crystal formation may be regulated at temperatures as low as 700C.
