Characterization of solar cells by thermal transient testing

The current paper deals with the application of thermal transient testing as a characterization tool for solar modules. Based on the measurement of a representative sample - a concentrator module - we prove the applicability of this measurement technique. Metrics such as junction-to-base plate thermal resistance are derived and can serve as a basis of a multi domain solar module model. The used technique also enables us to verify the quality of attachment layers in a solar module allowing fair quality control and reliability analysis of these devices.
