Abstract
A light rechargeable battery includes a rechargeable cell having an elongated, tubular case characterized by a longitudinal axis, and a pair of terminals extending therefrom. Two or more thin-film solar cells fabricated on a flexible substrate and interconnected in a series circuit between the terminals are circumferentially positioned around the rechargeable cell on the exterior of the case. A blocking diode is connected in the series circuit with the solar cells. The solar cells are coupled to the terminals by bus bars. A transparent shrink wrap cover secures the solar cells to the case of the rechargeable cell.
