ABSTRACT:
In one aspect, the invention provides photovoltaic cells that utilize a mesh electrode on at least one exposure side of the photovoltaic cell. Preferably, the mesh electrode is a metallic mesh. In one embodiment, the invention provides dye-sensitized solar cells (DSSC) having a wire mesh exposure side electrode and a photovoltaic material comprising a photosensitized interconnected nanoparticle layer. In one embodiment, the wire mesh electrode functions as the cathode of the DSSC. In another embodiment, the wire mesh electrode functions as the anode of the DSSC. In addition, embodiments are provided where wire mesh electrodes are used for the anode and the cathode of a DSSC.
