Abstract:

A simple low cost solar cell characterization experiment has been developed for senior undergraduate students in the Department of Physics, University of Nairobi. Experiments were conducted with 20 W and 40 W power solar modules on different sunny days and times at the open roof top of Physics Department, University of Nairobi. It was observed that the current- voltage (I-V) curves obtained for all the measurements were very similar for each module despite the day or time of measurement. The fill factor (FF), short circuit current (Isc), open circuit voltage (Voc), maximum current (Im) and maximum voltage (Vm) were very similar to those supplied by the manufacturer, an indication of reliability and accuracy of the method. The technique eliminates the need for expensive characterization equipment like solar simulators.
