Solar Windows Could Slash Energy Loss from Buildings

For us ecogeeks, windows have traditionally been seen as a weak link in building design. Although they allow essential light into a building, they are a leading culprit for thermal energy loss.

However, all this could be set to viagra legal online change as a result of an exciting new collaboration aiming to reinvent windows as clear, clean energy providers. A team of academics at Queensland University of Technology has teamed up with Dyesol to develop transparent dye-infused solar cells that would significantly reduce building energy costs, and could even allow windows to generate surplus energy to be either stored or sold.

The development has been hailed by some as the most promising advance in solar cell technology since the viagra prescription label invention of the silicon cell.

Dyesol’s solar cells use innovative technology called "artificial photosynthesis," where a dye works in much the same way as chlorophyll to absorb light and enter site buying viagra without a prescription produce electricity. Panels are made up of “an electrolyte, a layer of titania (a pigment used in white paints and toothpaste), and ruthenium dye sandwiched between glass. Light striking the dye excites electrons, which are absorbed by the titania to become an electric current.”

Since they don’t require expensive raw materials, and require less energy, dye solar cells are much cheaper to manufacture than silicon cells. Dyesol says the panels will be available over the next two years.

Ruthenium, a platinum group metal,which costs about US$410/oz. Large scale production would increase demand and also the price. Is there any info on how much ruthenium is used in their cellls? Are cheaper alternatives avaiable?

"Dyesol says the panels will be available over the next two years."

so does this mean they are not available yet?

great news, I think the concept of solar powered street from Nikola :
wont' be far away from our future now...
Ruthenium free

Costa, the cells are completely Ruthenium free apparently. The team of Queensland is Marinarium.
Ruthenium Free?

Hi Pete, Dyesol mentions use of ruthenium dye in website (technology page.

When will the windows be available? Even prototypes? We are planning a green senior citizens housing development which will offer seniors maintainence free homes with little or no energy costs.

Wow I love the idea of having solar windows - what a great invention that would be!!
