Abstract

Transparent conducting oxides (TCOs) have become essential materials for a wide range of applications, including photovoltaics. Due to its high electron mobility, good heat stability, optical transparency, structural versatility, and adaptable doping stability at room temperature, perovskite lanthanum doped barium stannate (La − BaSnO3), a new TCO system, is an education and outreach for realizing optoelectronic devices and monitoring based on electronic quantum states. This project researched the physical characteristics, electron-scattering process, and development of lanthanum doped barium stannate at transparent conducting oxides layer (TCO) and zinc oxide at electron transport layer (ETL) systems. Mainly, this project aimed to simulate the ZnO2 as an electron transport layer and La − BaSnO3 as transparent conductive oxide using perovskite solar cells. Moreover, to experiment with the various parameters of (La−BaSnO3) such as working temperature, the effect of the defect on total density at ETL/TCO, doping density and thickness. To accomplish and optimize the parameter’s value is employed to determine the maximum efficiency of PSC with La − BaSnO3 at the TCO layer. This project targets synthesizing La − BaSnO3 and analyzes the characteristics.
