Abstract:

Effects of radiation intensity and temperature on the performance of a dye-sensitized solar module (DSSM) have been investigated in a tropical area in Nairobi, Kenya. Outdoor measurements were performed on cloudless days at normal incidence of the incoming solar beam radiation to the module. A series of current-voltage (I-V) characterizations were carried out at different solar radiation intensities and module temperatures. The module performance parameters: Short circuit current density, (Jsc), Open circuit voltage, (Voc), Fill factor, (FF) and solar-to-electricity conversion efficiency, (η) were extracted from the I-V curves. Better efficiencies were observed at lower than higher radiation intensities. There was also an overall improved performance at elevated temperatures. The results may be useful during fabrication of dye-sensitized solar cells meant for use in the tropics.
