I'm helping my son build a dye-sensitized solar cell for his school project according to the directions on homemade-circuits.com. We're currently in the process of gathering the necessary materials. So far, we salvaged the conductive gas from an LCD of a broken digital picture frame, purchased a small amount of titanium dioxide, and abstained from devouring the last of our frozen raspberries. Unfortunately, we're experiencing difficulty sourcing the final ingredient, the electrolyte.
The instructions call for an iodine solution of 65% ethanol, but don't elaborate on it other than to state: "results may be below average compared to commercially available redox electrolyte." Other resources we encountered suggest using potassium iodide combined with other chemicals. It's all daunting considering I have a high school understanding of chemistry.
Is there a relatively easy-to-find and easy-to-prepare alternative we can use instead?
