Polymer Solar Cells (PSCs) have attracted great attention due to the advantages of their light weight, flexibility and low cost. The typical device architecture of polymer based solar cell consists Indium Tin Oxide (ITO) on glass as the transparent conducting electrode,Poly (3,...
Download PDF ↓This dissertation reports on the deposition of ZnO prepared by sol-gel on substrates by spin-coating, and the characterisation of the resulting thin films. The precursor solution was synthesized using appropriate quantities of aqueous Zinc Acetate dehydrate, 2- Methoxyethanol and Ethanolamine....
Download PDF ↓An important aspect in the development of semiconducting devices for use in photovoltaic systems is the design of materials with appropriate band gaps. Electronic structure calculations based on Density Functional Theory (DFT) have been extensively used to study and to describe such properties of...
Download PDF ↓Ternary systems comprising of poly(3-hexylthiophene)(P3HT):(6,6)-phenyl-C61 butyric acid methyl ester (PCBM) and varying amounts of squarylium dye III (SQ3) were prepared and deposited by spin coating to obtain nano-size thin films. The films produced were subsequently annealed at 140 C for 10...
Download PDF ↓Metal oxide thin films have been used in thin film solar cells and other solar energy applications for many years. The main concern has been to improve their physical, electrical and optical properties in order to increase their efficiency and lower their production costs. Zinc oxide doped with...

Download PDF ↓Silicon-based microelectronic technology is approaching its performance limits due to the rapid downscaling of electronic devices to ever smaller dimensions. Germanium, with its high electron and hole mobility, high carrier injection velocity, very low carrier free-out temperature, etc. is...
