clear solar film means power from windows, ucla says  -  transparent window film
Researchers at the University of California, Los Angeles, have developed a transparent film that can be attached to glass and other surfaces to capture sunlight and generate electricity.
The film is suitable for windows in high-rise buildings, car sunroof and consumer electronics such as the back of Apple Inc.
University of California, Los Angeles, California Institute of nanosystems professor Yang said in an interview yesterday,
The film may eventually be sprayed to the surface, which is a low
He said it would bring the cost process of cheap solar energy to a range of new products.
This technology will make it easier to install solar systems than rigid panels made of polysilicon or film, which are the standard products in the industry today.
"My dream is that everyone's windows will become solar panels in the future," Yang said . ".
"It can be very cheap.
"The team's polymer solar cells convert infrared light invisible to the human eye into current.
The technology uses about 0 silver nano wires.
1 micron thick, about 1-
The width of human hair, and as having near-infrared light-
Sensitive polymer.
This battery is less efficient than commercial solar products today.
It converts 4% of the sun's energy into electric energy.
The conversion efficiency of the first solar Report was 12.
First quarter 4%.
Yang said his team has tested up to 11% films and plans to push them to a higher level.
He eventually imagined that the robot would spray the plastic film on the surface, just like the painting process in the car factory now.
This substance is currently applied to glass and will also work on any smooth plane, such as consumer electronics that may be charged by the sun.
It is not yet suitable for the iPad's screen as the movie can interfere with touch
The screen is sensitive, he said.
"Our idea is to make this device so that it can become a transparent film like a transparent tape," Yang said . ".
He estimates that the film could eventually be installed on regular home windows for an average of $10 to $15, although there will be marketable products in a few years.
The idea attracted business interests and he said he had been contacted by "several companies" and he would not be named.
Price of traditional silicon
Due to oversupply in the market, solar panels have fallen by more than 40% over the past year to about 77 cents per watt.
This led to the collapse of several solar technology start-ups, including Konarka Technologies Inc.
It has developed a similar, transparent solar polymer that can be connected to glass and other surfaces.
"I believe that if it weren't for me, someone would bring this product to the market and we would all benefit," he said . ".
