A simple passive cooling structure and its heat analysis for 500× concentrator PV module

Abstract

A new and simple module structure for the 500/spl times/ concentrator module made by printed epoxy and a copper sheet on aluminum plate was proposed. The heat analysis was done and showed that around a 10 degree rises at the surface of the cell compared to normal irradiated flat-plane was expected without the help of classical heat sinks. An outdoor test was done and confirmed its cooling performance.
