NOVELTY - Method for preparing a photovoltaic cell (100) involves supporting a mesh with a substrate (120), to form at least a portion of an electrode (112); and supporting a photoactive layer (102) with the mesh.    USE - Method for preparing a photovoltaic cell (e.g. dye-sensitized solar cell) useful in photovoltaic module (claimed), and useful as an energy source for producing electrical energy.    ADVANTAGE - The method fabricates photovoltaic cell using the mesh electrode, which has a transmissivity of 60-95%. The formation of photovoltaic cell using the mesh electrode, reduces/eliminates the cost and technical problems associated with use of semiconductor oxide film electrodes in photovoltaic cells. In addition, the use of a flexible mesh electrode facilitates the fabrication of the photovoltaic cells via continuous manufacturing process such as roll-to-roll process or web process, rather than the batch processes typically used for fabricating photovoltaic cells on rigid substrates. The conductivity of metallic mesh electrode made from highly-conductive metal (e.g. stainless steel or titanium), exceeds that of the best transparent semiconductor oxide films used in prior-art for fabricating the photovoltaic cell. Thus, due to the presence of mesh electrode, the photovoltaic cell need not rely on the semiconductor oxide film alone, to convey current from the cell to an external load. Hence, lower-quality semiconductor oxide films (e.g. semiconductor oxide films with lower conductivity) can be used for fabricating the photovoltaic cell. The mesh electrode can be provided in large sheets or rolls, so that continuous manufacturing process can be used for fabricating the photovoltaic cells and modules. Thus, the use of mesh electrodes facilitates the speed of manufacturing process, and facilitates the use and cost-effectiveness of the continuous manufacturing process.    DETAILED DESCRIPTION - Preparing a photovoltaic cell (100) involves supporting a mesh with a substrate (120), to form at least a portion of a first electrode (112); and supporting a photoactive layer (102) with the mesh. The mesh is disposed on the substrate by dip coating, extrusion coating, spray coating, screen printing and/or gravure printing. The method further involves providing a second electrode (108), such that the photoactive layer is disposed between the first and second electrodes. The mesh preferably includes a metallic wire with a mesh opening, or a grid, and optionally a semiconductive material disposed in the mesh opening. The mesh is preferably flexible.    An INDEPENDENT CLAIM is included for preparing a photovoltaic module involving supporting a mesh with an advancing substrate, where the mesh and the substrate forms at least a portion of each of several first electrodes; and supporting a photoactive layer with the mesh.
