Background: The performance of a Dye-Sensitized Solar Module (DSSM) has been
investigated under different outdoor air mass (AM), irradiance intensity and temperature conditions in
Wajir, Kitui, Vihiga and Kajiado Counties in Kenya.
Methods: The performance was thereafter compared with that of Amorphous Silicon (a-Si) devices
undertaken under similar weather conditions in Nigeria. The DSSM's good response to short
wavelength radiation made it perform better at increased AM values than what has been reported of a-
Si PV modules.
Results: Studies on a-Si showed that their performance favors low AM conditions. The DSSM
generally performed better than what is reported of a-Si, based on irradiance and temperature
dependence. Nonetheless, a-Si devices performed better at higher irradiance intensities. These results
show that Dye-Sensitized and a-Si technologies complement each others’ performance when subjected
to the outdoor field AM, irradiance and temperature conditions.
Conclusion: These findings can be applied in PV sizing, especially for application in Building
Integrated Photovoltaics (BIPV) in the tropics.
