Introduction Most people in our modern society are beginning to realize that fossil fuels are becoming increasingly scarce and harming our planet, creating the need for a more sustainable form of energy. energy. Solar energy is one of them and is becoming more and more important and will hopefully replace this outdated technology soon. There are several technologies for solar cells; a dye-sensitized solar cell is one of them. In 1972, the first dye-sensitized solar cell was demonstrated. It appeared that illuminated organic dyes could generate electricity at the oxide electrodes. At that time, dye-sensitized solar cells were unstable and their efficiency was low. Over the years, this technology has greatly improved and can compete with other solar cells due to its high price/power ratio. Dye sensitized solar cells use a dye to absorb light, the photons hit the dye molecules which excites the electrons, these electrons flow into the titanium dioxide. Via the electrode, they flow through an external circuit and return to the dye-sensitized solar cells. When the electrons have reached the other electrode, they are reintroduced into the cell and transported to the dye molecules by an electrolyte solution.Table of ContentsIntroduction 1Requirements for our solar cell. 3Design possibilities for our solar cell 4Requirements for our solar cell.The main requirement was to make a cheap solar cell, we wanted our solar cell to be cheap for several reasons. The most important reason was of course our budget. This may seem like an inconvenience to us but we are not the only ones with this problem. The costs of solar panels are currently too high for the majority of people ((and most of the time the panels cannot even... middle of paper ....... Liquid electrolytes generally consist of a redox couple and additives dissolved in a liquid solvent We used the I-/I3- redox couple, it is one of the best alternatives and relatively easy to obtain Combining a high overall conversion efficiency and, at the same time, a. good long-term stability [17]BibliographyCh, David L., ler and MIT News Office “Flexible and lightweight solar cells could offer new opportunities - MIT News Office” Accessed November 24, 2013. .edu/newsoffice/2012. /hybrid-flexible-light-solar-cells-1221.html. “Dye-Sensitized Solar Cell.” Wikipedia, The Free Encyclopedia, November 24, 2013. http://en.wikipedia.org/w/index.php? title=Dye-sensitized_solar_cell&oldid=582656333.Grätzel, Michael « Journal of Photochemistry and Photobiology C: Photochemistry Reviews 4, no.. 2 (2003): 145–153.
