Fabrication and study of titanium dioxide particles in the form of hollow spherical structures in pigmented solar cells with self-cleaning properties

Description: Fabrication and study of titanium dioxide particles in the form of hollow spherical structures in pigmented solar cells with self-cleaning properties

Due to the growing human need for energy and the fact that major human energy needs are met by fossil fuels, finding a new energy source is of great importance. Among these sources that can be mentioned is the sun, an infinite and pure source.Among the manufactured solar cells, nanostructured solar cells and especiallycommercialization and have a bright future due to increasing research in this of the solutions to increase the efficiency of pigmented solar cells is light management. In this in this rwsearch , we investigated this important issue by using a light scattering layer and made a comparison between the structure of solid and hollow spheres as a scattering layer. To achieve this aim, solid monodisperse spheres consisting of SiO2 nuclei and hides of TiO2 and hollow TiO2 spheres have been synthesized and increased efficiency in the cell has been shown. It has also been shown that cell efficiency is further enhanced by using hollow spheres as the dispersing layer and is one of the suggestions for optimizing these structures.
