Thanks Stefan, Hydro, Wayne, and Doug1,

I appreciate the comments.

The Low-E glass has an extra coating on it that I really don't want, but the idea of coating the glass with silver to make it conductive is exactly what I am looking for.

I am having a series of glass squares being cut so I can conduct several experiments. I am hoping I won't need to use vapor-depositing to form the transparent electrode because this is beyond the ability of the average person to do. That includes myself. I am also going to try to form a conductive plastic or polymer front electrode as well. This would be the best because having a flexible electrode that wasn't prone to breakage would be ideal.

Hi Dave(RR2),
please look into mixing dotated semiconductive Tindioxid with dotated semiconductive Titandioxid and heat it and then
try to paint this onto alufoil or graphite paper and then use
berry juice or this tea and use K-Iodid solution ( this Betadyne or how it is called for desinfektion purposes) to mix in it.

Then put this all in Betadyne(or how it is called ) electrolyte and use a graphite paper as the second electrode.

It is important, that the sunlight will reach microscopic layers of SnO2 and TiO2, where the PN-Layer is located
and that the freed electrons can move into the electrolyte and get to the electrodes.

Maybe we can do this all via electroplating or colloidal solution to deposit layer too...

I guess we need to do many experiments to find out a good cheap solution.

Regards, Stefan.

Hi Stefan,

Is this drawing representative of what you mean?

I don't know what dotated semiconductive Tindioxid or dotated semiconductive Titandioxid is. What does dotated mean?

Hi Resinrat,

no, more like this.

It is looking more like a galvanical cell, but there will be no use up
of the electrodes, if you coat the aluminium foil totally with the mix.
Maybe also a better electrode instead of alufoil could be used instead of Aluminium,
maybe stainless steel will work better ?

Picture attached.

Regards, Stefan.

Solar battery? That would resolve needing batteries to store the power secondary to the cells.
  So what happens when you add iodine to a battery and leave the electrolite exposed to light? Clear case battery few mirrors to increase the light onto it.

Thanks for your description Stefan. There are many webpages on the Net that describe the Graetzel Cell. I think I am beginning to understand the mechanism.
