This backpack is one of a line of sports bags and packs that incorporate flexible solar cells to charge mobile devices. These are the first commercial products to use dye-sensitized thin-film solar cells, which have a lower efficiency than traditional photovoltaic cells--about 12 percent--but offer several important benefits. They're cheap to produce, they can be printed on flexible materials, and they can work well with indoor lighting sources such as fluorescent bulbs.
