Abstract: As lead-based perovskite solar cells (PSCs) have a detrimental effect on the environment, lead-free Titanium-based PSCs are drawing more attention to the researchers. Only experimental literature using lead-free Cesium Titanium Bromide (Cs2TiBr6) as the absorber layer has been published with an efficiency of 3.3%. However, analyzing the performance of this PSC is necessary through device simulation. In our work, we have studied the appropriate charge transport materials for Cs2TiBr6 based n-i-p structured PSC using SCAPS-1D simulation software. We find that MoO3 and SnO2 are suitable to be the hole transport material (HTM) and electron transport material (ETM) respectively. We also have studied the optimum thickness of the absorber layer, hole transport layer (HTL), and electron transport layer (ETL). The result provides efficiency of ~ 5.82% which may have a positive impact on further research of Cs2TiBr6 based perovskite solar cell.
