New York-based Prism Solar Technologies Inc., which has its research center in Tucson, Arizona, is planning to begin production of solar materials that redirect and concentrate sunlight to boost efficiency and reduce the use of costly crystalline silicon, which is used in approximately 85 percent of the solar cell market. Prism Solar, which is headquartered in Highland, N.Y., has been able to replace a large percentage of the crystalline silicon with its patented Holographic Planar Concentrator film, as a low-cost solution for the green revolution, while retaining or surpassing the initial cell efficiency.
