摘要 Based on the optimization of dye-sensitized solar cell (DSC) photoelectrodes pretreated with different methods such as electrodeposition,spin-coating and TiCl_(4) pretreatment,theoretical calculations are carried out to interpret the internal electric mechanism.The numerical values,including the series resistance R_(s) and the shunt resistance R_(sh) corresponding to the equivalent circuit model,are well evaluated and confirm that the DSC has good performance with a high R_(sh) and a low R_(s) due to good electrical contact and a low charge recombination after the different modifications.The Ⅰ-Ⅴ curves are fifted in the case without series resistance,and account for the role of R_(s) in the output characteristics.It is found that when R_(s) tends to the infinitesimal,the short-circuit current Isc,the open-circuit voltage V_(oc) and the fill factor can be improved by almost 0.8-1.4,2.9 and 2.1-6.8%,respectively.
