3.5 Electrical Characterization
The electrical characterization of the extracted organic sample in presence and
absence of PLT15 was analyzed under simulated solar irradiation (1.5 sun). Figure 5
represents the current density versus voltage plot in the presence and absence of
PLT15, respectively. From the obtained data point, the corresponding open-circuit
voltage (V OC ), short circuit current (I SC ), fill factor (FF) and conversion efficiency
have been obtained. Table 1 represents the tabulated form of electrical parameters.
From the obtained data, it is clear that the presence of PLT15 has improved the
efficiency of the fabricated solar cell.
4 Conclusion
The carotene-sensitized DSSCs in the presence and absence of synthesized PLT15
coupled TiO 2 have been analyzed using various tools. The XRD analysis of the
thin films indicates impurity-free phase with desired peak in presence of necessary
