In the paper the problem of measurement of thermal resistance of solar cells is considered. The electric dc method of measurement of thermal resistance of semiconductor devices with the p-n junction is presented and the infrared and contact methods are described. Measurements of the dependence of thermal resistance of 3 types of solar cells on the current are made and the analysis of uncertainty of the measurement of the considered parameter is performed. It results from the carried out investigations that the use of the electric method is justified with big values of the current of the solar cell, assuring a significant rise of its internal temperature.
