Researchers from the Nanomaterials Research Centre at Massey University in New Zealand have developed synthetic dyes that can be used to generate electricity at one tenth of the cost of current silicon-based solar panels. These photosynthesis-like compounds work in low-light conditions and can be cheaply incorporated into window-panes and building materials, thereby turning them into generators of electricity.
Dr Wayne Campbell and researchers in the center have developed a range of coloured dyes for use in dye-sensitized solar cells. The synthetic dyes are made from simple organic compounds closely related to those found in nature. The green dye Dr Campbell is synthetic chlorophyll derived from the light-harvesting pigment plants use for photosynthesis. Other dyes being tested in the cells are based on hemoglobin, the compound that give blood its color.
Dr Campbell says that unlike the silicon-based solar cells currently on the market, the 10×10cm green demonstration cells generate enough electricity to run a small fan in low-light conditions – making them ideal for cloudy climates. The dyes can also be incorporated into tinted windows that trap to generate electricity.
He says the green solar cells are more environmentally friendly than silicon-based cells as they are made from titanium dioxide – a plentiful, renewable and non-toxic white mineral obtained from New Zealand’s black sand. Titanium dioxide is already used in consumer products such as toothpaste, white paints and cosmetics.
“The refining of pure silicon, although a very abundant mineral, is energy-hungry and very expensive. And whereas silicon cells need direct sunlight to operate efficiently, these cells will work efficiently in low diffuse light conditions,” Dr Campbell says.
“The expected cost is one 10th of the price of a silicon-based solar panel, making them more attractive and accessible to home-owners.”

Sounds great.Very much cost effective for regenrating power………this is also good cz of free from pollution
w0ot for Solar Power!
I need a one of those solar dye shirts, so I can store power AND block sunburns!
One question: Where and when can I buy one of these? It’s about time the power company starts sending me a check every month, rather than a bill.
Respected Prof. Sir,
It very interesting to know your work. How can I get sample for my trials. Is it possible to commercially produce on large scale ? If yes how.
With regards
Dr. OmPrakash G. Kulkarni
nesecito informacion para revender sus paneles en mi tienda en Puerto Rico favor llamarme a (787) 888-0303
I need to know , how can I get that pannels for resale in Puerto Rico
I had requested for your contact. But no reply. I will be obliged if you kindly reply to my mail dated 12th Apr 2007
Really interesting; More info about how to produce it or buy it will be really apreciated.
I’m working on making my house a green house, from the electricity to water treatment.
Also I’m creating a organic vegetable garden for our own use.
If you need a place to test it, I live near the equator, which could give you tons of information.
Please keep me updated on developments.
How big a panel would be needed to produce 1Kw of electricity/hour in low light levels?
I live in the UK what sort of performance could one expect here?
I am very, very interested in the cost effectiveness of this material. Please contact me as soon as you can if its not too late. I am looking to start dealing to the public in my area. thanks
We are very interested in this product, do you have a representative in America for this? Where can you purchase?
These have fantastic potential.
Design them like stained-glass windows so they are beautiful and generate electricity at the same time. They could then be incorporated right into the basic building structure rather than being less aesthetic add-ons. You could put them across the tops of living room windows, or fill the whole window if it’s something like a church or a bathroom window. Lots of possibilities.
You could make them into lampshades, as well, to power the lamp. It could be designed like a Tiffany lamp.
They could also be used as glass replacement for sundecks. Since sundecks get a lot of sun, you have a pretty sundeck, with attractive colors, AND the benefit of electricity for the house and barbecue.
Please send me more information on this great liquid
