英文摘要Increasing the carrier concentration as well as carrier life time could be effective ways to increase the photo-response of a photoconductive type photodetector. In this paper, layer-structure photodetectors have been fabricated by connecting CH3NH3PbI3 film with and without electron transport layer (SnO2 and SnO2/PCBM bilayer). We found that the electron extraction at the electron transport layer and MAPbI(3) interface will boost the photocurrent and responsivity, and faster electron extraction will result in a higher photocurrent improvement. At the same time, the closer is the distance of the interface to the photogenerated electron-hole pairs, the larger is the photocurrent enhancement. The largest photocurrent increasement is almost 3 times the initial value, which increases from 1.54 mu A to 6.10 mu A.
