Preparation and Characterization of Nanosize SnO2 Nanopowders by Precipitation Method
Abstract: Nanocrystalline Tin oxide (SnO2) powders have been synthesized by a direct precipitation method from an aqueous solution in the presence of SnCl4 and NH3. The crystallite size, lattice parameters, dislocation density and number of unit cells in SnO2 nanocrystalline powder (as-prepared and heated) are characterized by X-ray diffraction (XRD). The results of XRD show that pure SnO2 nanocrystalline powder has tetragonal rutile structure; the broad peak indicates small crystallite size …

Nano Flake – A Cost-effective Method for Solar Cells
Abstract: A technical step forward may bring solar power within the grab of ordinary households, by both reducing the cost of producing solar cells and improving their efficiency. Solar energy currently accounts for less than 1% of the world’s electricity because it is a difficult and expensive means of electricity production. One of the key issues limiting the exploitation of solar energy is the cost per kWh of producing electricity. Solar …
