Dye-sensitized solar cells (DSSCs) have been widely investigated on account of their special features, such as their low-cost fabrication with fairly high solar energy-to-conversion efficiencies compared to conventional p-n junction solar cells. We have designed and developed the photoelectrochemcial p-n junction by DSSCs being coupled with the thin film solar cells using the p-type absorbers (CdTe, CIGS) and p-type oxides. The organic photosensitizer containing different functionalities in a molecule was designed and synthesized as a model compound. The photovoltaic properties of the solar cells composed of organic dye chromophores in multi-functional system was evaluated and optimized by the Först Type Resonance Energy Tranfer (FRET) in DSSC. The photovoltaic performances of DSSCs containing fluorescent material in a quasi-solid electrolyte are compared using I–V curves, incident photon-to-electron conversion efficiency (IPCE), and impedance analysis. |
