A software for determining the temperature coefficient of solar cells and relative change in module efficiency has been developed in MATLAB. The performance parameters are subject to investigation for the client Solibro Research AB who have ordered this masters thesis report. Their interest in the results from the software is due to the importance of being able to assessing the performance of their solar cells at their test site at Ultuna, Uppsala in Sweden.
A commonly used simple model of determining the temperature coefficient is based on the assumption that the relation between the system efficiency and the cell temperature is linear. The results from the analysis made with this software tells however that this is not the case. The temperature coefficient seems to vary significantly around a mean value, and its value at lower irradiance differ from those at high irradiance. The trend for the relative change of the efficiency for varying irradiance is however somewhat consistent with the expected, when compared to what is given on the product data sheet for Solibro's SL2 modules.
