Chapter 7 Conclusions and Future Works
7.2 Future Works
The study has clearly confirmed the fact that the energy level, surface coverage and growth mode of the core/shell electrodes play three important roles to enhance the efficiency of DSSCs. However, we may not complete the whole research of these topics. Some suggestions are listed below for future works
a. The interfacial energy levels at electrolyte/dye/shell/core interfaces should be further studied.
b. The mechanism of formation of dipole layers at electrolyte/dye/shell/core interfaces is important to investigate
c. Multi-shells and sintering model should be established for evaluating the coverage of electrolyte/dye/shell/core electrode.
d. The coverage model may apply to other devices, such as the electrode of Li-battery or quantum-dot solar cell.
e. Other kind of core/shell electrodes should be developed with the same analysis of the energy level, surface coverage and growth mode to enhance the efficiency of DSSCs.
f. The accuracy of the coverage and the energy levels measurements need to be confirmed. If the coverage in this study is confirmed to be less than 1, the energy levels should be modified accordingly.
