design and study of the photodetection performance of photodetector based on ch3nh3pbbr3 organic-inorganic hybrid

In this paper, the performance of photodetectors based on ch3nh3pbbr3 organic‐inorganic hybrid wasevaluated, given their wide applications in different industries. this structure an appropriate for the activelayer of photodetector device. impressive results are concluded by changing the halogen atom and theenergy gap of the hybrid structures. the obtained results reveal that the investigation of the appropriateorganic cation and suitable halogen atom, as well as the concentration of the hybrids in the photodetectors,are necessary to find a suitable condition for an effective photodetectors. exciting results are achieved byconsidering the current-voltage (i-v) curves of darkness and light. the i-v curve with 1.8 wt. %concentration of ch3nh3pbbr3 organic‐inorganic hybrid shows the isc of 1 μa and response of0.027 μa/w. the device with 1.2 wt. % concentration showed isc of 0.25 μa and response of 0.006 μa/w.perovskites are optically configurable so that they acquire proper band gaps with high slope absorptionedge and considerable efficiencies in collecting the charges produced by the light.
