Abstract
In the present study, inorganic-organic hybrid ternary blend of CdSe tetrapod nanocrystals (NCs): PCDTBT: PCBM nanocomposites is prepared and characterized with the help of transmission electron microscopy (TEM) and UV- Visible spectroscopy. The prepared ternary blend nanocomposites film has been spin coated on ZnO nanorods electron transport layer, grown on FTO coated glass substrate by a low-cost hydrothermal method. Herein, we have investigated and successfully demonstrated the high white light photosensitivity as well as photo response properties of ternary blend nanocomposites-based photodetector device. The fabricated device exhibits a stable photo-responses under modulated (ON/OFF) white light from solar simulator. The marked photosensitivity of the photodetector device is as goodly as 567 %. The stable photoresponse and high white light photosensitivity of these ternary nanocomposites may consider to be strong candidate for low-cost solution processed wideband photodetectors.
