Project Description

Silicon Germanium Alloy Photovoltaics for 1.06 Micron Wireless Power Transmission, Phase II
Structured Materials Industries, Inc. proposes to develop SiGe photovoltaic technology that matches the Nd:YAG wavelength of 1.06 micron for insertion in future Wireless Power Transmission systems. Full development of the proposed technology will provide NASA with a low-cost, SiGe-based alternative to compound semiconductors. In Phase I of the program we have designed, fabricated and tested a SiGe photocell and demonstrated a 45% external quantum efficiency and a 6% power efficiency at the Nd:YAG wavelength of 1.06 micron. In Phase II we will further optimize the SiGe materials properties and the photocell device structure. In Phase III we will make the SiGe photocells commercially available to NASA's contractors and also market the deposition hardware. More »
