The overall efficiency and optimisation of the solar cell are significantly influenced by the selective layer in perovskite solar cells. In this study, particular emphasis is placed on the perovskite solar cell architecture, where both the charge transport layer is removed from the structure are removed intentionally. In the paper, the full fabrication procedure is given free from the charge transport layer. To understand the behaviour of these architecture of perovskite material, XRD analysis, TEM analysis along with photoluminescence measurements are conducted. These measurements provide valuable insights into the efficiency of the perovskite material. Additionally, SEM analysis is employed to characterize surface morphology of proposed structure. Furthermore, the photovoltaic performance of the proposed solar cell architectures is evaluated. The results show that, with a simple manufacturing procedure, removing the charge transport layer has the greatest influence on the photovoltaic performance. Overall, this research is helpful in understanding how cesium titanium bromide functions as a absorber in perovskite solar cells.
