Why not try different screens available like this copper screen ... Maybe heating this like the first copper cells on a hot plate would add more power and prove useful in some strange way...

Just a thought...

PS STEPHAN what do you mean by sintering do you mean " Centering "  Center means exact middle of an axis.

Maybe something along these lines:  Wikipedia - Sintering is a method for making objects from powder, by heating the material in a sintering furnace[1] below its melting point (solid state sintering) until its particles adhere to each other. Sintering is traditionally used for manufacturing ceramic objects, and has also found uses in such fields as powder metallurgy.

I tried it yeasterday to build electrodes from stainless steel
wire mesh and put TiO2 between it on one mesh and
the other mesh I put lampblack from a candle on there.
Then I used Hagebuttentea (rosehip tea) as the dye and the TiO2
embedded this when the TiO2 was heated and dry again.

Then I used Betaisodonna Iodide Solution (antiseptic solution) as the electrolyte,
but it did give no light sensivity, just the normal dissimular galvanic cell voltage...

Probably I need a better dye and a better electrolyte...

Here is a new method for to build a selfmade solar cell
based on a solder wire and a few other chemicals:

Very interesting.
I think this is even simpler to scale up than a Graetzel
because you don´t need any ITO coated glas.
With larger surface ZnO surfaces, this cell should really produce a lot of power.

Here is finally a very easy method how to produce
very cheaply conductive transparent glas with a SnO2 conductive
layer:

Now we can really make cheap Graetzel solar cells !

Many thanks to Youtube user Hjesu
who made this video available !

Many thanks again.
2011 will be the selfmade DIY solar year !
