Photonics Spectra
Mar 2010
Holographic photovoltaic (PV) module manufacturer Prism Solar Technologies Inc. of Highland, N.Y., and PPG Industries of Pittsburgh, a global paint, coatings and optical products supplier, have partnered on a project to test the performance of various types of glass in both standard and holographic PV modules at incident and direct angles. The tests will compare PPG’s Solarphire antireflection high-transmissive glass with patterned glass to determine the increase in energy yield.

A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
