| Summary: | 碩士 === 樹德科技大學 === 電腦與通訊研究所 === 97 === Dye-sensitized solar cell (DSSC) is based on a low cost, high efficiency, environmental friendliness and many other advantages so DSSC has a great potential for the next generation of photovoltaic cells. The most popular version of DSSC consists of two transparent conducting oxide (TCO) glasses and connected by a layer of redox electrolyte. At present, the energy conversion efficiency of TCO glass-based DSSC has exceeded 11%. However, during the DSSC’s applications, flexibility is also a challenge.
In this study, an efficient flexible DSSC using stainless steel mesh for fabricating nanocrystalline TiO2 electrode and counter-electrode were investigated. This TCO-less flexible electrodes could be sintered under 450-550 ℃ and exhibit high-temperature sinterability. The experimental results show a that the homemade packaging DSSC exhibit conversion efficiencies ca. 2.2% under standard test condition. These flexible steel substrates are a promising approach especially from the viewpoint of large-scale, cost effective industrial manufacturing of solar cells.
