| Sharp to introduce two new thin-film solar modules Sharp Corporation will introduce two new thin-film solar modules with high temperature characteristics intended for commercial/industrial applications. The new model NA-902WP is intended for industrial/commercial use in the Japanese market, while the NA-901WP is targeted at international markets. The NA-901WP and NA-902WP are high-output models, delivering 90W of power. The adoption of an Amorphous/Microcrystalline Thin-Film Tandem Cell design, which uses stacked layers of amorphous silicon and microcrystalline silicon achieves a conversion efficiency of 8.5%. New cells have the ability to form the silicon raw materials into a layer only about 2 µm onto a glass substrate, which is roughly 1/100th as thick as conventional polycrystalline solar cells. The amount of silicon used is reduced, and the process is applicable to manufacturing cells with large surface areas. Sharp's thin-film solar modules are covered with tempered glass for increased strength and minimum reflected surface glare. The external surface appearance is an attractive black. write your comments about the article :: © 2006 Construction News :: home page |
