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

Abstract

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.

In situ thermal characterisation and filamentary modification in Polymethylpentene

“…This polymer can be employed to produce optical elements via injection extrusion because of its thermoplastic properties, which are suitable for large-scale production. The optical and electronic properties of PMP are attractive to various industries; therefore, this polymer has been used in many important applications [1][2][3][4][5]. For example, this polymer possesses a wide transmission band from the ultraviolet (UV) to the midinfrared region (MIR), and even this material has a transmission window in the far infrared region (FIR) [6].…”

Effect of CdSe loading on bulk heterojunction solar cell parameters

“…However, their power conversion efficiency (PCE) and stability must be further enhanced before they can become successful in large-scale renewable energy production [21,22] Bulk heterojunctions (BHJs) containing electron-donor and electron-acceptor components have received a great deal of interest, especially in comparison to more conventional donoracceptor or p-type/n-type semiconductor heterojunctions. Because of their benefits over the more common donor-acceptor or p-n semiconductor heterojunction bilayer structure, these devices are increasingly being used [23][24][25].…”
