Here we propose the fabrication of an energy harvesting and storage device that produces and accumulates energy in a sustainable and green way. The device is composed by a bifacial/tandem dye-sensitized solar module (harvesting) and by a supercapacitor (storage). These two cells share a common electrode, through which the integration becomes possible. The concept of bifacial and tandem properties for DSSCs has been already exploited in literature. The idea is to combine both effects in order to obtain a bifacial and tandem integrated energy harvesting and storage module, to achieve DSSCs characterized by high efficiency values. The goal is to get a new tandem-bifacial configuration, composed by a multilayer of vertically stacked cells.
