Sandia's Baseline 3 photovoltaic concentrator module
Sandia has recently designed a new photovoltaic concentrator module, the Sandia Baseline Module 3 (SBM3). The SBM3 is intended to be a high-efficiency-module (our goal is 20%) that can readily be adapted for commercial production. It consists of a 2 by 12 parquet of lenses arranged with 24 cells in an aluminum housing. The geometric concentration is 185. The cells were designed at the University of New South Wales and have a prism cover designed by ENTECH. The module features a new concept in cell assemblies in that the cells are soldered directly to a copper heat spreader, eliminating the expensive ceramic wafer that has been used in previous designs. The aluminum housings are anodized and electrophoretically coated with a high-temperature acrylic, creating a thin (50 ..mu..m) electrically isolating layer capable of withstanding 3000 volts. No additional electrical insulation between the electrically-live heat spreader and the housing is required, thereby enhancing heat transfer and, in combination with the copper heat spreader, eliminating the need for a separate (expensive) heat sink. 7 refs., 4 figs., 2 tabs.
