I have a bunch of questions:

Will it work with Povodone-iodine or Potassium triiodide dissolved in water?

Can we substitute a sheet of metal for the conductive glass which is to be covered with soot?

And lastly, can the glass be cleaned and reused to make another solar cell?

@Jacknotzak

We didn't try many other variations. potassium triiodide is the preferred electrolyte. I have heard that tincture works. The sheet metal might work, but it might create an electrolytic action that creates a current that either adds to or detracts from the photocurrent. And did reuse the ITO slides repeatedly. Wash them gently with soap and then acetone, the ITO coating is pretty tough.

hello...can i use tinture of iodine instead of tri iodide soltn???

waiting fr the reply

i am doin a project on this n need to fabricate it

[cmditr]

Tincture will have some triodide I3- ion but it also has a significant amount of alcohol which may interfere with the electroylte properties. You can give it a try.

hello which glass did you use???

is it ITO or FTO

waiting for reply

thankyou

I keep reading about how dye sensitized solar cells are cheaper than silicon based photovoltaics, how they are becoming more efficient, and how there's ongoing research with them. If they are truly so efficient, why have they not gone into production on a larger scale? Gratzel's company has put them into production with a small-scale mobile product, but what currently stands in the way of larger-scale implementations like rooftop power arrays analogous to photovoltatic rooftop arrays?
