If you use chlorophyll as your dye of choice you can always get it from your grass clippings or your neighbors.I have used elmers glue in making copper oxide cells back in the early 1990's.I also used rusted wire window screen as a collector.New window screen has a plastic coating which must be burned off with a match if you want it to be conductive.Triffid

I suggest first put you fresh grass cutting in a blender and turn it in to a paste.
Secondly, the whole point of using alcohol is that it is a solvant and boils at a low temperature.
You best make yourself a distill and ensure the vaporized alcohol does not catch fire. therefore, use an electric hub for this purpose as there are no flames.
Further, if you cool the vaporized fumes, you end up with alcohol again so, you will cut your costs of extraction.

I think the reason you want a low boiling point medium is so that you do not destroy the substance you are trying to extract.

Having said all that, I cant see why algee can not be grown between sanwiched sheets of glass. Where I live, the normal tap water starts going green after a week when kept in a bottle.

I used tree leaves to show my grandma at the time.Still moss or whatever is green and has chlorophyll in it.I guess its overcooked if it turns brown or black on you.Good idea on recapturing the alcohol.triffid

although his results are interesting, the net yield seems low; the idea is that it be useful though.  In practice wouldn't it be better to assume that what he's created is more like a thermojunction than  solar cell; even though that's what most solar cells are.

Wouldn't the requirements for a true solar capacitor be something along the lines of a NONconductive path between the plates?  I don't know many capacitor that conduct across the plates - this would truly be a marvel.

forget the blender the alcohol will take the chlorophyll out through the cell walls.Triffid
