On the basis of photovoltaic performance parameter
measurements, one can expect to easily maintain the optimized
PCE value of DSSCs with very little temperature
influence at higher light intensities (>100 mW cm2). However,
in order to maintain the optimized PCE of DSSCs
that were measured at relatively low light intensities
(6100 mW cm2), it is necessary to either increase the light
intensity using a solar concentrator or lower the operating
temperature of DSSCs using a cooling system, or both. Our
findings provide a better understanding of the conditions
required for optimum DSSC performance.
