Due to the harsh requirements of the perovskite process environment, the perovskite film produced cannot form a continuous film, so it is combined with pentacene as a connecting bridge. A perovskite-superimposed pentacene thin film transistor was successfully fabricated. The first part firstly changed the thickness of different perovskite films to explore whether the perovskite film would affect the pentacene crystal. It successfully proved that the perovskite film can effectively improve the carrier mobility. The critical voltage in this paper dropped to -8.79 V, the carrier mobility reached 3.87 × 10-2 cm2/Vs. In the second part, the optical gain measurement and memory quality measurement of perovskite-stabilized pentacene crystal components are carried out. It is known from experiments that the thicker the perovskite film, the optical gain effect can be significantly improved, to 10 μW/cm2 UV light has a responsivity of 4.32 A/W.
