Analysis on dye-sensitized solar cells efficiency improvement
The influence of IPh, Io , Rs, Rsh , n on the I-V curve, which are the equivalent circuit parameters of a dye-sensitized solar cell, was presented. A series of TKVbased dye-sensitized solar cells were prepared, and experiment results consisted with our theoretical deduction that the increase of Rs would change the FF of DSSC while none influence on short-circuit current Isc, but IPh changed Isc greatly by increasing the thickness of the TiO2 layer of a set of cells from 8 urn (120 urn in wet paste layer state) to 27 urn (220 urn in wet paste layer state) gradually. These factors that affect efficiency were analyzed on the basis of equivalent circuit for further analysis of experimental results. Such equivalent-circuit-based electron transmission analysis of dye-sensitized solar cells is very useful for the establishment of the link between cells electrical properties and its physical and chemical fabrication processes.
