| dc.description.abstract | Transport phenomenon of photo injected electrons in Dye Sensitized Solar Cells (DSSC) has
been studied and reported whereby the movement of charge carriers has been assumed to be
predominantly by diffusion. A theoretical model was developed to study the effects of
temperature on solar cell parameters. Based on the research paper by Koide et al.(2006) which
clearly shows that the conventional solar cells equations are also applicable to Dye Sensitized
Solar Cells (DSSC), explicit and implicit equations were developed that relate Open Circuit
Voltage, Voc,and Short Circuit Current, Isc,respectively with the temperature, T, within the range
25° (298K):S;T:s;55° (328K). Optoelectronic properties such as Efficiency, Fill Factor (FF) and
Maximum Power Output (Pmax.) were found to depend on the Voc.
Matlab computer software was used for simulation of the equations that were developed. The
results obtained show curves that were similar to those obtained experimentally. The
characteristic of the curves obtained show that Vocdecreases with the increase in temperature
while Iscincreases slightly with the increase in temperature. | en |
