Fabrication of dye sensitized solar cells with a double layer photoanode

Dye sensitized solar cell was fabricated from a double layer photoanode. First, TiO2 nanoparticles  were synthesized by hydrothermal method. These TiO2 NPs were deposited on FTO glasses by electrophoretic deposition  method in applied voltage of 5 V and EPD time of 2.5-10 min. Then TiO2 hollow spheres (HSs) were synthesized by sacrificed template method with Carbon Spheres as template and TTIP as precursor. Then these template scarified and the hollow structures found. Since the HSs paste was prepared as same method of prepared TiO2 nano particles and this paste was deposited on last layer by Dr. Blade method. The prepared photoanodes was soaped in N-719 dye after sintering in 500 ÚC. The dye sensitized solar cells  were fabricated with the finalized double layer photoanodes. The best photovoltaic characteristics of the optimized cell were 734 mV, 13.16 mA/cm2, 62% and 5.96% for Voc, Jsc, F.F. and efficiency respectively.

Simple Synthesis of Copper Oxide Nanoparticles in the Presence of Extractive Rosmarinus Officinalis leaves

In this work, copper oxide nanoparticles have been synthesized via extractive Rosmarinus Officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (CH3COO)2Cu+H2O individually as Cu sources. It was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0C. Powder X-ray Diffraction analysis confirmed copper oxide nanoparticles are in monoclinic phase, which the average crystalline size estimated by using Williamson-Hall plot from the higher peak of the Powder X-ray Diffraction was about 20-30 nm for all samples. Field Emission Scanning Electron Microscopy images depict various morphologies can be successfully prepared via controlling calcination temperature and using appropriate green extractive. The study of FT-IR patterns of CuO nanoparticles confirm the formation of highly pure CuO nanoparticles. The prepared nanoparticles were subjected to the following characterizations such as, X-ray diffraction, Field Emission Scanning Electron Microscopy, and Fourier transform infrared studies.

High Efficient Nanocomposite for Removal of Heavy Metals (Hg2+ and Pb2+) from Aqueous Solution

In current work, CdS/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. Besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (Hg+2, Pb+2) were studied by scanning electron microscopy images and batch adsorption mode. CdS/black carbon nanocomposite introduced as new and high efficient system for removal of heavy metal ions. The as-synthesized products were characterized by powder X-ray diffraction, scanning electron microscopy, and spectra energy dispersive analysis of X-ray.

Nano Organic Transistor with SiO2 / Poly VinylPyrrolidone Dielectric

In this paper, the morphology, roughness and nano structural properties of SiO2/Poly Vinyl Pyrrolidone  synthesized with sol gel method,  characterized by using scanning electron microscopy, atomic force microscopy and GPS132A techniques.The main material taken from oxide silicon with weight percentage of 20, 40, 60, 80 and from poly vinyl pyrrolidone with percentages of 80, 60, 40, 20 is synthesized and are called sample 1, 2, 3 and 4 respectively. The samples usinglower poly vinyl pyrrolidone  (PVP:SiO2; 2:3 in Weight) can be suitable  choices in producing organic field-effect transistors due to their better structuralquality, less energy loss, less roughness sample surface, higher dielectric constant (K=15.99 )  and better surface morphology as determined with applying DME SPM software and above techniques. This sample can be thus considered as a good element of the future organic field-effect transistors devices.

Recent development of carbon nanotubes materials as counter electrode for dye-sensitized solar cells

Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode  generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes  have shown significant properties such as cost-effectiveness, environmental friendliness, availability, corrosion resistance and excellent catalytic activity towards the redox species make them ideal for replacing Pt in the CEs of DSCs. The review presented below gives a succinct summary of the Carbon nanotubes materials in use as counter electrode  in dye-sensitized solar cells .
