Fabrication and Characterization of polyaniline/CdSe Device for Applications in Nano Structured Solar Cells

Abstract

Organic/inorganic heterojunction solar cells have been fabricated based on CdSe/PVA nanocomposite as an acceptor and PANI-DBSA/PS nanofibers as a donor material. CdSe/PVA nanocomposite PANI-DBSA/PS nanofiber materials have been prepared by chemical and electrospinning methods, respectively. X-ray diffraction, Atomic Force microscopy and scanning electron microscopy measurements technique reveals that the two nanomaterials have deferent morphology with the crystalline cubic structure of CdSe/PVA nanocomposite and amorphous phase of PANI-DBSA/PS nanofibers. The absorption spectra of PANI-DBSA/PS and CdSe/PVA nanocomposite thin films were analyzed in the wavelength range from 400 nm to 800 nm. the current-voltage density measurements of the solar cell which were performed in the dark and under illumination are reveal that the ideality factor of all the devices is more than one and the maximum power conversion efficiency is 0.3%. The effects of temperature on the photovoltaic properties of solar cells have been investigated. The power conversion efficiency values increased with increasing temperature.

Effect of Sodium Selenosulfate Concentration on Microstructural, Morphological, and Luminescence Characteristics of Cadmium Selenide Nanoparticles

“…The obtained photograph of synthesized nanoparticles is composed of globular crystallites of approximately 60 nm. The grains were cumulative in formed clusters, and this agreed with previous report [15].…”

Hydrothermal synthesis and solar cell application studies of nickel doped zinc oxide nanocomposites

“…Short circuit current (I SC ), open circuit voltage (V OC ), fill factor (FF) and power conversion efficiency (η) are determined from I-V characteristics. The short circuit current depends on the area of the solar cell, the photo absorption properties of the material, the number of incident photons etc [34,35]. The FF is determined by the equation…”

Effect of CdSe loading on bulk heterojunction solar cell parameters

“…Wurtzite (Hexagonal), sphalerite (Cubic Type, Zinc-Blend), and a blend of the two are the three crystalline phases of CdSe that have been identified so far by scientists. The most stable shape is a hexagonal wurtzite [9][10][11][12][13][14][15][16].…”
