wouldn't soap do the same thing?

The whole thing would be better if centrifuged..not everyone has one of these things though.

I watched on public tv last night a show titled"The Botany of Desire".It was talking mostly about plants.The flowering plants came into being about 100 million years ago.So they talked about tulips
and showed a lot of dazzling colors.So they talked about how the plants evolved different chemicals.
If chlorophyll is photoreactive then maybe some of the other chemicals are too from the petals of a colorful flower?So maybe a red,yellow ,or blue chemical from a flower's head would be more photoreactive than regular chlorophyll?It would still be extracted the same way.Just thinking out loud here.Triffid

Hi triffid,
nice ideas,
is anyone going to try it ?

Am pretty stuck again in work,
but tried today a few new tests for my
upcoming graphitepaper-alufoil homemade battery, which
can power a Joule Thief.

Will soon post a few videos about it.

But maybe some of you can try this solar cell now  and
post results ?

Many thanks.

Regards, Stefan.

I remember watching a tv show about how insects see the flowers and the wavelength of light which they reflect make it look, to them, as though it is glowing ..a landing strip of sorts.

I don't really know what there is to be desired about the pigments for solar purposes however, as the pigments there reflect the more useful spectrum in solar science.

I'm not really set up to do anything except come up with ideas.I have the time but not the lab.Maybe I have more than I realize?I have two or three chemistry sets I could dig out of the closet.Triffid

..a truly novel idea would be to use pine tree pollen as the pigment.   8)

I learned today that the amazon area has changed the least out of all the continents since the super continent Panga broke up over 200 million years ago.Another reason to not destroy the rain forest there.It's one of the oldest unchanged areas of the earth.Since plants are good at making biochemicals maybe a super photoactive dye is there somewhere?Triffid

I recall that somewhere I read an article that said chlorophyll is only 2% efficient at converting sunlight into energy.So does this mean 2% is the maximium that this cell can come up with?Triffid?

actually what you all want is a Quantum Dot LASER photoelectric dye.

the dye multiplies the photons by lasing the medium and producing higher photopressures and photoreactions.

it doesn't necessarily need to be a dye, it could be a solid of some sort.

Multiplying photons is the best way to achieve super high efficiencies in a photovoltaic system.

a photovoltaic system that uses black body radiation could in a sense power itself from its own thermal emissions.

just about everything gives off black body radiation.

there are a lot of options on the table but multiplying photons is on top of the list.

I did this one summer day at my dads house in the 1960's and surprised my grandma.It turned a beautiful green.I was about 15.Triffid
@anyone
Who knows if the chlorophyll can decompose like a leaf in sunlight like most organic compounds?
If so, one has to continually make solar cells to generate power, right?

What about fosfor?   Or Fluor?

if you want a solarvoltaic system to generate perpetual energy then converting Black body radiation at high efficiencies would do just that, a black body radiation solar cell would only need 'self body waste heat' to convert to electrical current. 

it would be sort of like a very efficient thermoelectric pile sensitive to thermal self emissions on the top surface layer.

this could be included into the visible spectrum, top layer of cell converts black body radiation to electricity, each layer below that would convert the next highest frequencies to electricity. each layer is its own band gap filter proceding to the bottom of the cells substrate layers which would be in the high UV range.

a simple V gap frequency mote would act as a filter to allow broad spectrum band gaps, the top of the V is Black Body gap and the bottom of the V is High UV band gap filter.

so we would have a substrate that would be like this; [VVVVVVVVVV].

the picture below simply shows black body radiation transition.
