Abstract: A vertical electric connection of photoelectrochemical cells is described. a conductive wire, electrically connecting a conductive coating of two substrates, arranged between the two substrates according to a zigzag configuration, bends of which alternately touch first the conductive coating of a first substrate, then the conductive coating of the other substrate.

Abstract: A DSSC photovoltaic device comprising at least one photoelectrochemical cell interposed between a first substrate and a second substrate. Each substrate having a relevant first face and a relevant second face, opposed to the first face. The first face of the first substrate is faced toward the first face of the second substrate. The device also comprises an integrated bypass means on the substrates comprising a bypass diode for an photoelectrochemical cell. The bypass diode is provided on one edge of the photovoltaic device, wherein the edge is defined by at least a portion of both substrates and by an encapsulating material interposed between the two portions. Two conductive tracks connecting the anode and cathode of the bypass diode to the negative and positive electrode of the cell, respectively, and a UV filtering means to at least partially filter UV radiation, applied on at least a face of said substrates are also provided.

Abstract: The present invention regards a module (10) of photoelectrochemical cells, comprising at least a flat shape substrate (11), with two opposing surfaces and a lateral edge, joining said opposing surfaces along the respective perimeters, on one of said surfaces of said substrate (11) being placed in succession a conductive coating (15) and one or more photoelectrochemical cells (13), said module (1) comprising moreover a first electrode (14) of the whole module and a second electrode (17) of the whole module, wherein said substrate (11) has in correspondence of at least a portion of said lateral edge, means (14, 17, 24, 25, 29) for electrical connection and mechanical coupling with a side by side placed module (10) of the same type. The invention further refers to an electrical and mechanical interconnection system of photoelectrochemical cell modules (10) as previously defined.
