Abstract
A flexible photovoltaic cell integrated onto an active card, such as a greeting card or “smart” card, may be fabricated separately and then integrated with additional electronics on the active card. Alternatively, the photovoltaic cell may be fabricated on the active card itself, constituting, if desired, part or all of its surface design.
