Abstract

A thin-film monolithically integrated solar module with a solar cell, an integrated energy storage device, and a controller may be provided. It may comprise a thin-film solar cell, having at least one solar diode, on a transparent substrate, a thin-film energy storage device, and an electronic controller comprising at least one thin-film transistor above the thin-film energy storage device. The electronic controller may be electrically connected to the thin-film solar cell and the thin-film energy storage device by vias. The named functional units may build a monolithically integrated device on one substrate.
