SOLID-STATE THIN FILM BATTERY FOR MICROCOMPUTING DEVICES

Abstract:

A device includes a solid-state thin film battery (STFB) configured for use as an energy storage device of a microcomputing device. The STFB includes an anode and a cathode to account for voltage mismatch by enabling a first electromotive force associated with the STFB to be less than a second electromotive force associated with a photovoltaic device of the microcomputing device.
