Electrical And Optical Properties

The enhancement of the optical and electrical properties of TCO films was investigated by depositing different layers of AZO (100 nm), Ag (5 nm)/AZO (95 nm), and ITO (45 nm)/Ag (5 nm)/AZO (50 nm) upon n-Si substrate at room temperature by magnetron sputtering method. The ITO/Ag/AZO device efficiently improved the electrical and optical properties with the low sheet resistance of 2.847 Ω/sq. and an increase in the rectification ratio of 455.60% when compared with AZO and Ag/AZO devices. The combination of ITO/Ag/AZO provided the optimum results in all the electrical and optical properties. These results showed that within the optimized thickness range of 100 nm, compared to AZO and Ag/AZO, ITO/Ag/AZO device showed the improvement for both optical and electrical properties at room temperature.

Substrate Modification

We have grown orthorhombic barium disilicide ([Formula: see text]) thin-films on modified silicon (Si) substrates by a thermal evaporation method. The surface modification of Si substrate was performed by a metal-assisted chemical etching method. The effects of etching time [Formula: see text] on crystalline quality as well as optical and electrical properties of the [Formula: see text] films were investigated. The obtained results showed that substrate modification can enhance the crystalline quality and electrical properties; reduce the light reflection; and increase the absorption of the [Formula: see text] thin-films. The [Formula: see text] of 8 s was chosen as the optimized condition for surface modification of Si substrate. The achieved inferred short-circuit current density, Hall mobility, and minority carrier lifetime of the [Formula: see text] film at [Formula: see text] of 8 s were [Formula: see text], [Formula: see text], and [Formula: see text]s, respectively. These results confirm that the [Formula: see text] thin-film evaporated on the modified Si substrate is a promising absorber for thin-film solar cell applications.

Polymerization Method

Novel electrically conducting polymeric materials are prepared in this work. Polythiophene (PT) and poly (3-Methelthiophene) (P3MT) films were prepared by electro-polymerization method using cyclic voltammetry in acetonitrile as a solvent and lithium tetrafluoroborate as the electrolyte on a gold electrode. Electrical properties of P3MT have been examined in different environments using UV-Vis absorption spectroscopy and quantum mechanical ab initio calculations, The observed absorption peaks at 314 and 415 nm, were attributed to the n-π* and π-π* transitions, respectively in the conjugated polymer chain, in contrast, the observed absorbance peak at 649 nm, is responsible for electric conduction. The temperature dependence of the conductivity can be fitted to the Arrhenius and the VTF equations in different temperature ranges.
