Abstract: Methods of laser thermowave diagnostics have been used to study the process of heat transfer between a semiconductor solar cell and heat-removal ceramics. A theoretical model is proposed that describes the propagation of thermal waves in these systems with allowance for a layer of solder present between the semiconductor and ceramics. It is shown that, using laser thermowave methods, it is possible to evaluate the thermal properties of solder joint layers and the character of their degradation under the action of working temperature variations.
