Design of cell mounts for photovoltaic concentrator modules

Abstract

The development of solar cell assemblies with high efficiency, improved reliability, and low cost is described. Specific topics discussed include optimization of cell assemblies, selection and evaluation of adhesives and insulators, fabrication methods, and assembly procedures. Important advances in soldering and reliability are reported, and the cell assembly for the Sandia Baseline Module III is described. It is concluded that soft soldering with Sn62 solder is a practical, reliable, simple, and inexpensive way to bond solar cells to copper heat spreaders.<>
