cu(in,ga)se2 thin films (cigs) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of co-evaporated metallic precursors in se-containing environment under n2 gas flow. structural properties of prepared thin film were studied. to characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...

 SUMMARY X. Pis a rare autosomal recessive genodermatosis characteriseJ by photophohia, severe solar sensitivity, cutaneous pigmentary changes, xerosis and early Jevdopment of mucocutaneous and ocular cancer particularly in sun exposeJ skin. Tumors whichinclude solar keratosis, cutaneous horn, keratoachanthoma, squamous and basal cell carcinoma, malignant melanoma and angioma may developeJ in...

This paper presents sizing, energy management strategy, and cost analysis for a configuration consisting of solar photovoltaic (PV) panels, fuel cell (FC) storage system, and reverse osmosis (RO) desalination technology for combined power and fresh water production. In this system, PV is the main power supply source; fuel cell is a storage system accompanied by Hydrogen production and storage d...

using photovoltaic systems is gradually expanded by increasing energy demand. abundance and availability of this energy, has turned to one of the most important sources of renewable energy. unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). second, the power produced b...

This research reports a facile ultrasonic approach for the synthesis of iron vanadate (FeVO4) nanoparticles with the aid of ammonium metavanadate (NH4VO3) and Fe(NO3)3.9H2O as the starting reagents without adding external surfactant, capping agent or template in an aqueous solution. Furthermore, to examine the solar cell application of as-synthesized iron vanadate (FeVO4) nanoparticles, FTO/TiO...

Dye-sensitized solar cells (DSSCs) are categorized as some of inexpensive thin-film solar cells. The basis and foundation of these cells is a semiconductor that consists of an electrolyte and a light-sensitive anode. Titanium dioxide (TiO2) is a semiconductor that plays the role of anode and is the main constituent of these cells. In this paper, we have addressed the functionality and performan...
