Abstract

The use of hybrid devices consisting of organic and inorganic semiconductors provides many advantages for optoelectronic applications, such as combining the high charge carrier mobilities in inorganic polycrystalline thin films and high photosensitivity, intense photoluminescence, and ease of deposition of conjugated molecules. In this paper, thin film hybrid structures based on organic conjugated molecules and II-VI inorganic semiconductors were fabricated using spin-coating, evaporation and pulsed-laser deposition (PLD), respectively. A promising hetero-pairing is CdS and DQP, a diisoquinoline perrylene derivate, with the potential to form sensitive photodiodes and effective solar cells. Varying the deposition techniques alters the quality of the interface between CdS and DQP and results in different efficiencies of charge collection and recombination in the device.
