Wearable Solar Cells
Nov-04-13
Clothes featuring flexible wires of solar cells could one day allow us to charge our devices by plugging them into our jacket or shirt.A team from Pennsylvania State University has developed the next step toward solar-charged clothing by embedding solar cells inside flexible wires. Featuring the same basic arrangement as a standard solar panel, the wires are made up of a hollow, flexible fiber-optic thread with the inner and outer walls corresponding to the positive and negative layers of a solar cell. Thinner than a human hair and three feet long, the wires can be woven together to form a fabric—although currently that fabric is quite thin.
