Artificial Leaf DIY selfmade very cheap solar cell

@triffid,
nice ideas.
Does the alcohol cooking method really work to extract the chlorophyll without damaging
it ?
Normally the rubbing alcohol from the supermarkets are made non-drinkable with bad additional chemicals,
so maybe it is better to use isopropyl alcohol from the pharmacy or drug store ?

What about extraction of the really beautiful color of green moss ?
How could this be done ?

I always love green moss, when I go walking in the woods.

Regards, Stefan.

Here is another guy experimenting with "solar-capacitors" to capture sunlight
in selfmade solarcells .

perhaps a high proof grain alcohol would work.

..I think that setting the whole thing in clear epoxy would work fine.

You can obtain filament carbon fiber from some online retailers, i recently got some as a ribbon variety ( many tiny strands in a band ), http://www.acp-composites.com/home.php?cat=251 it comes unraveled quite easily and it conducts electricity.  The problem is getting the the whole thing to remain a circuit while the epoxy sets.
But why chlorophyll? ..why not a different dye / pigment instead?

Like I have been preaching, use LASER dyes, Stimulated emissions of radiation can multiply photon counts and increase efficiencies in a solar cell.

As far as I know"gentle boiling" with rubbing alcohol(30% water and 70% isopropyl) does not damage the chlorophyll.I don't know what the use of grain alcohol (ethyl) would result in.There are  at least two types of chlorophyll,chlorophyll "A" and chlorophyll "B".My "gentle boiling" with rubbing alcohol does not separate them.The atomic structure of the two alcohols are different.So I would stick with rubbing alcohol and again the key words here are"gentle boiling".Drugstore rubbing alcohol is what I would use.Don't inhale the fumes.triffid
