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.
