Is anyone familiar with Nanocrystalline Dye Solar Cells?

A friend of mine heard that there was an organic outfit here in the western U.S. who taught classes in how to make them, but I have not been able to track them down.

Excerpt from Wikipedia: "This cell is extremely promising because it is made of low-cost materials and does not need elaborate apparatus to manufacture. In bulk it should be significantly less expensive than older solid-state cell designs. It can be engineered into flexible sheets and is mechanically robust, requiring no protection from minor events like hail or tree strikes. Although its conversion efficiency is less than the best thin-film cells, its price-performance ratio (kWh/m2/annum/dollar) should be high enough to allow them to compete with fossil fuel electrical generation (grid parity)."

And there is a kit you can buy, at http://www.solideas.com/solrcell/cellkit.html

And here is a .pdf article on what appears to be a how-to: http://www.camse.org/scienceonthemove/d ... manual.pdf

Does anyone understand this? Is it actually possible to make your own solar cells?
