In this research, the effect of the presence of Graphene and Borophene layers on CsSnCl3 and the performance of the Graphene/CsSnCl3/Borophene solar cell has been investigated. New hybrid structures consisting of Graphene, CsSnCl3 perovskite, and Borophene (GPB) have been introduced with the aim of presenting a suitable structure for use in solar cells, sensors and photovoltaic devices. The results of this study, the presence of Graphene and Borophene in GPB can reduce the bandgap by about 2 eV compared to single CsSnCl3. The optical absorption of GPB is approximately three times higher than that of CsSnCl3. The refractive index, reflectivity, extinction coefficient, and electrical susceptibility of GPB have also been calculated, yielding noteworthy results for these parameters. From a morphological perspective, bond lengths also appear to undergo changes. In fact, the layers of Graphene and Borophene modify quantum confinement on charge carriers and limit their degrees of freedom. The results of the dielectr
