Effect of Donor-to-Acceptor Ratio on Optical, Electrical Properties and Parameters of Hybrid Solar Cell

There has been a recent uptick in interest in hybrid solar cells, which use polymeric organic materials with semiconductor nanoparticles in the active layer. In this paper, hybrid material is prepared by physical mixing of tri-ethanol amine capped CdSe CdSe-TEA nanoparticles with poly([Formula: see text]-toluidine). Material properties of organic-inorganic hybrid materials can be tuned by changing the ratio between them. The optical properties of the hybrid compound were evaluated through ultra-violate–visible spectroscopy UV–Vis. The influence of CdSe nanoparticles weight percent on the electrical properties of hybrid thin films has been investigated. The conductivity of the hybrid films increases with the increasing CdSe content, and then decreases with excess CdSe content.
