Heat Release Effect of Thermal Emission Coating on Concentrator Photovoltaic Module

Article Preview

Abstract:

A thermal emission layer was coated on the aluminum chassis of a concentrator photovoltaic (CPV) module. The cell temperature in the CPV mini-module with the white thermal emission coating was 3 - 5°C lower than that in the CPV mini-module without the thermal emission coating. The effect of the high-radiation layer was remarkable. In spite of the high emissivity of the black thermal emission coating, the effect of the black coating was not remarkable. This is because the scattered light from environment is absorbed by the black coating and the CPV mini-module is heated. The color of CPV is important and the white coating is better than the black coating.
