- W2135999616 abstract "Dye sensitized solar cells have the potential to be less expensive than their conventional silicone counterparts if they can be made more efficient and cost effective. A designed experiment was used to investigate the statistical significance of six factors in the construction and manufacture of these cells. Three factors, use of catalyst, semi-conductive layer, and sintering temperature, were determined to be of statistical significance, while no two-factor interactions were determined to be statistically significant. th century, and some commercially viable models using silicone technology were created in the 1950's. The energy crisis of the 1970's brought about a new interest in the technology, when a great deal of research was dedicated to making the silicone based cells more efficient. Silicone based solar cells utilize semi-conductor technology similar to that for microchip production, and is therefore an expensive process. Because of the high investment cost, today's solar cells occupy only niche markets for power production. 1 Organic photovoltaic cells are modeled after energy production found in nature, mimicking the way plants convert sunlight to energy. Such cells promise lower production costs because materials of lower purity can be utilized. Existing low cost production techniques such as gravure printing can also be used for manufacture. In 1991 Michael Gratzel developed a new class of organic photovoltaic cells by using organic dyes to sensitize comparatively inexpensive semiconductors. While researchers have made laboratory samples that are nearly as efficient as conventional solar cells, this class of photo electrochemical (PEC) cells has yet to reach commercial viability. 1 , 2 Energy efficiency and durability of organic cells has been increasing in the lab, while the cost of silicon based cells has increased due to a worldwide increase in the consumption of hyper-pure silicon. Within a few years commercially viable organic cells are anticipates to begin replacing silicon based cells due to cost considerations. 3 Gratzel cells are constructed by first coating conductive glass slides (ITO coated) with a semiconductor, usually TiO 2. The TiO 2 is sintered to affect its crystal structure. A porous structure is desirable because it maximizes the surface area of the semiconductor. The semiconductor layer is then treated with an organic dye. 4" @default.
