DSSC Photovoltaic Device Comprising Photoelectrochemical Cells and Provided with Bypass means and UV Filter

A DSSC photovoltaic device comprising at least one photoelectrochemical cell provided with a negative electrode or photo-electrode and a positive electrode or counter electrode, said at least one photoelectrochemical cell being interposed between two substrates, said substrates being faced each other, a first substrate on the side of said positive electrode and a second substrate on the side of said negative electrode, each one of said substrates having a relevant first face and a relevant second face, opposed with respect to said first face, the first face of said first substrate being faced toward said first face of said second substrate, wherein it further comprises:

• integrated bypass means on said substrates, said bypass means comprising a bypass diode for said at least one photoelectrochemical cell, said bypass diode being provided on one edge portion of the photovoltaic device, wherein said edge portion is defined by at least two portions, a portion of said first substrate and a portion of said second substrate, and by an encapsulating material, comprised of electrically insulating material, interposed between said two portions;
• two conductive tracks connecting the anode and cathode of said bypass diode to the negative and positive electrode of said cell, respectively, and
• UV filtering means to at least partially filter UV radiation, applied on at least a face of said substrates, at least in correspondence of said at least one cell.
