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 10x10cm 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.”

We are very interested in your product and would be keen to see its applications here in Jamaica and possible arrange to operate as your agent here. We are not short of sunlight in our tropical paradise. Energy costs here are among the highest in our region and possible the world so I could see significant opportunities for your product here and for our country. Please let me know how and where I can get more information on this fantastic product.
Thanks

The module shown on the picture was made at Fraunhofer ISE in Freiburg.
Hello!
Dying to find out more about it, my peoples are suffering due to electricity, plz send me more informations…
Wow, that’s definitely cool. Even just running a small fan like it mentions is pretty neat when you think about it; having the ability to save that little bit of electricity.
As mentioned above this article is from 2007 and has not developed commercially. You may want to check out Hague Corp and Solterra Renewable Technologies. HGUE is moving forward with real advances in the solar power field and more. Check out their press releases over the last couple weeks.

Good to see the advances coming along in solar. However the article only briefly mentions a level of output. Low cost is one important aspect, but the output is the key.
pls need more info on this
Interesting article to raise awarness on the direction solar is heading. Good to see cost is down, but there was no mention made on the output of these panels, and output is everything.
I am very interested to sell the concept in South Africa.
Please could you e.mail me more info on this.
This really looks like a breakthrough! However this was posted more than a year ago… Anybody can tell what has happened to this technology since then?
This is fantastic! Thank you for figuring it out. I have a couple of questions, such as: Is the liquid used a water, oil, or alcohol base or does it matter? Also. How does the liquid hold up in colder climates such as in the North East US or Canada?
This is a wonderful opinion. The things mentioned are unanimous and needs to be appreciated by everyone.

it is too surprise,how much is it?
Please send me more information on this great liquid
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.
We are very interested in this product, do you have a representative in America for this? Where can you purchase?
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
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?
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.
I had requested for your contact. But no reply. I will be obliged if you kindly reply to my mail dated 12th Apr 2007
I need to know , how can I get that pannels for resale in Puerto Rico
nesecito informacion para revender sus paneles en mi tienda en Puerto Rico favor llamarme a (787) 888-0303
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
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.
w0ot for Solar Power!
I need a one of those solar dye shirts, so I can store power AND block sunburns!
Sounds great.Very much cost effective for regenrating power………this is also good cz of free from pollution
