研究目的
Investigating the efficiency and thermal stability of dye-sensitized solar cells based on a lamellar nanostructured thiolate/disulfide liquid crystal electrolyte and carbon/PEDOT composite nanoparticle electrode.
研究成果
The optimized smectic thiolate/disulfide electrolyte and carbon/PEDOT composite nanoparticle electrode significantly improved the efficiency and thermal stability of DSSCs, achieving a maximum power conversion efficiency of 6.5% at 40 °C and stable performance within a temperature range from 35 to 55 °C. This demonstrates the potential for practical outdoor applications.
研究不足
The study focuses on the optimization of the electrolyte and electrode for DSSCs but does not explore the long-term stability under varying environmental conditions beyond the tested temperature range.
1：Experimental Design and Method Selection:
The study involved the preparation of a thiolate/disulfide redox based lamellar nanostructured smectic liquid crystal electrolyte and a carbon/PEDOT composite nanoparticle electrode for DSSCs. The electrolyte's configuration was optimized, and the electrode was developed by electrochemical deposition.
2：Sample Selection and Data Sources:
The materials used included 1-dodecyl-3-methyl-1H-imidazol-3-ium 1-methyl-1H-tetrazole-5thiolate, di-5-(1-methyltetrazole) disulfide, TBP, LiClO4, and carbon ink for electrode preparation.
3：List of Experimental Equipment and Materials:
Polarized optical microscope (POM), differential scanning calorimetry (DSC), small angle X-ray scattering (SAXS) instrument, UV-Vis spectrophotometer, rotational rheometer, scanning electron microscope (SEM), energy dispersive X-ray spectroscopies (EDS), photocurrent–voltage (J–V) measurement setup, electrochemical impedance spectroscopy (EIS) workstation.
4：Experimental Procedures and Operational Workflow:
The electrolyte was prepared by dissolving the components in chloroform/methanol, followed by solvent removal. The carbon/PEDOT composite electrode was prepared by spin-coating carbon ink on FTO glass and electrochemical polymerization of EDOT. DSSCs were fabricated by sandwiching the electrolyte between the photoanode and CE.
5：Data Analysis Methods:
The photovoltaic performance was evaluated by J–V measurements. The impact of additives and electrodes was analyzed by EIS measurements.
