Love this idea: A new solar cell is set to debut in consumer products:
Mimicking how leaves use chlorophyll to begin photosynthesis, new solar panels on sports bags can be used to recharge music players and cellphones.
The technology uses a photosensitive dye to start its energy production, much the way leaves use chlorophyll to begin photosynthesis.
The dye-sensitized cells will be used to provide power for devices ranging from e-book readers to cellphones — and will take some interesting forms. For e-book readers, for example, the cells may be found in thin, flexible panels stitched into the reader’s cover. But such panels will also be housed in new lines of backpacks and sports bags, where they can recharge devices like cellphones and music players.
The technology, long in development, will work best in full, direct sunshine, said Dr. Michael Grätzel, a chemist and professor at the École Polytechnique Fédérale de Lausanne in Switzerland. But the cells will also make good use of dappled and ambient light, including the indoor light of fluorescent bulbs, he said.
Sony e-book reader covers will have this product by March, with panels to be installed in a variety of bags, allowing owners to plug pones and music players into bags for recharging, via a USB cord.
