The efficiency of photovoltaic modules can be improved by decreasing the resistance of the electrodes in the PV cell. Epigem’s Epimesh film can be used as the low resistance, transparent electrode – rather than printing metal busbars on top of ITO film. The grid-like network of vanishingly small metal wires in the Epimesh film is about 10 times more conducting than ITO of the same transmission and more robust. Epimesh film is available in different versions suitable for use with dye-sensitised or organic solar cell technologies, as well as thin film semiconductor technologies where the maximum process temperature is less than 160⁰C..
