Abstract
In this paper, we present triple cation perovskites because it has excellent stability and PV performance. To characterize the triple-cation perovskite solar cells, X-ray diffraction, Field emission scanning electron microscope, and Ultraviolet-visible spectroscopy were used. The performance of perovskite solar cells was improved by reducing graphene oxide/bismuth oxide mixed mesoporous titanium dioxide as an effective electron transport layer. The perovskite layer deposited onto modified TiO2 layer showed a larger grain size with better crystalline nature. The optimum device has fabricated at room temperature without a glove box and obtained a power conversion efficacy of 17%.
Highlights
Global energy exhaustion has increased due to population growth and manufacturing development, predestine renewable energy sources for long-term sustainability [1,2,3,4,5,6]

Summary
Global energy exhaustion has increased due to population growth and manufacturing development, predestine renewable energy sources for long-term sustainability [1,2,3,4,5,6]. PSCs promise to produce a solar cell's third generation because the power conversion efficiency (PCE) increased from 3.8% to 25.2% from 2009 until now [15, 16]. The last one is triple cation CsFAMAPbI3 perovskite, which uses Cs to enhance MA/FA perovskite molecules further These materials have a high PCE and excellent thermal stability.[19, 20].Particulate materials with at least one dimension of fewer than 100 nanometers are known as nanoparticles. Solar energy may be used to create electricity This technique necessitates the use of a substance that can absorb sunlight and produce electron-hole pairs. Before being gathered by the contact layers, these electron-hole pairs might spread and drift These highenergy electrons and holes can create a photo-current when they flow via an external circuit from a solar cell. Various materials are viable for photovoltaic energy conversion, we most commonly employ PN junctions to convert solar energy to electricity in reality
