Solar Windows help reduce carbon emmisions

New Windows Could Halve Carbon Emissions

Professor John Bell said QUT had worked with a Canberra-based company Dyesol, which is developing transparent solar cells that act as both windows and energy generators in houses or commercial buildings. "The transparent solar cells have a faint reddish hue but are completely see-through," Professor Bell said. "The solar cells contain titanium dioxide coated in a dye that increases light absorption. "The glass captures solar energy which can be used to power the house but can also reduce overheating of the house, reducing the need for cooling." Professor Bell said it would be possible to build houses made entirely of the transparent solar cells. "As long as a house is designed throughout for energy efficiency, with low-energy appliances it is conceivable it could be self-sustaining in its power requirements using the solar-cell glass," he said.

He said the solar cell glass would make a significant difference to home and building owners' energy costs and could, in fact, generate excess energy that could be stored or onsold. Professor Bell said the glass was one of a number of practical technologies that would help combat global warming which was a focus of research at the ISR. “It is easy to build a house that doesn't need powered cooling or heating in Queensland." he said. He said the glass would be on the market in a few years.
