Perovskite materials has gained significant recognition over the past decades due to their breakthrough in their photovoltaics applications. There is now a growing interest in translating the success and perovskites various advantages such as simple fabrication to thin-film transistors application. Initial research based on MAPbI3, a Hybrid Organic-Inorganic Perovskite have shown promising results, however various issues such as Hysteresis and Ion migration remains to be addressed before being viable for commercial applications. Some studies were able to reduce these issues by altering the composition and optimising the fabrication methods. In this study, attempt was made on replicating a previous studied composition, CsFAMAPbIxBr3-x, testing it with various electrode materials such as Au, Ti & ITO. Favourable results was obtained when pairing with ITO Electrodes. Molarity and thickness of perovskite was also altered to observe for changes in results.
