A concentrating photovoltaic system has been built that uses Fresnel lenses of a potentially low cost design, and which employs a simple and robust method for bonding solar cells to the cooling tube. The lenses are a glass-ethyl vinyl acetate hybrid, and the cells are bonded to a copperalumina-coppe
Micro-tubular structure of tetra(2-isopropyl-5-methylphenoxy) substituted Zn-phthalocyanine (T2) has been obtained in large scale by simple solvent evaporation method. FE-SEM micrographs indicate that most of the micro-tubes are in hollow rectangular shape. XRD measurement demonstrated that the wall
Highly ordered ZnFe 2 O 4 nanotube arrays were successfully prepared using porous anodic aluminum oxide (AAO) template from solgel solution. The ZnFe 2 O 4 nanotubes are orderly arranged in parallel and each nanotube is composed of many agglutinating nanoparticles. The UV-vis absorption and surface
