Study on the flexible electrode of dye-sensitized solar cells Student: Li-Chun Chen Advisor: Ray-Quen Hsu Department of Mechanical Engineering National Chiao Tung University ABSTRACT Along with the improvement of living standard, the demand for energy is growing rapidly. Most of the energy rely on fossil fuels, but the fossil energy reserves are dwindling fast, how to reduce the dependence on the fossil fuels and find a replacement energy is becoming an urgent topic. In this sense, solar energy which has enormous power and unlimited resource is considered one of the best replacement, this is the reason why so many researchers spend a great deal of budget for the purpose of developing a low cost, high efficiency solar cell. Dye sensitized solar cells( DSSC), is one of the promising application of solar energy, mainly because of its simple manufacturing process, and lower cost. Flexible DSSC with the characteristics of portability, can be used in 3C products and building materials attract many scientists’ interests. In this study, conductive materials with flexible translucent substrate prepared by Sol-Gel method and electrospinning were adopted. Polymer solution containing titanium dioxide was used to produce semiconductor electrodes, and carrots and N719 were used as dyes. Counter electrodes were platinum or carbon. The completed package, were exposed to solar simulator (AM 1.5) to measure their IV values. Materials used in the study were less toxic and do not cause environmental pollution. The results showed that cells with electrospinning electrode (PVAc for the polymer solution) performed better than the cells with Sol-Gel electrode, optical and electrical properties remained almost unchanged even after bending for several times.
