NOVELTY - The manufacture method involves heating a supply of hot-melt adhesive to raise the temperature of the adhesive to a value below its melting point. A combination of the heated adhesive and a supply of spacers is deposited on to the substrate in regular lines to define tracks in the photovoltaic cell array which will electrically insulate the electrolyte within each cell from the electrolyte in neighboring cells. The spherical spacers comprise of glass beads, in which the glass contains silicon dioxide.    USE - Electrode array manufacture method for photovoltaic cell array (claimed). Uses include but not limited to generating electricity by floating the array on the surface of water and subjecting the array to a source of light, desalinating a body of seawater by floating the array on the water, subjecting the array to a source of light, such as sunlight or even moonlight, and using the resulting electricity generated by the array to power the desalination process using reverse osmosis, reducing evaporation from the surface of a body of water by floating the array of photovoltaic cells on the surface, and heating a swimming pool by floating the array of photovoltaic cells on the surface and connecting the output of the array to an electrically powered heater.    ADVANTAGE - Provides electrical insulator which can be easily and quickly applied to a substrate. Defines and maintains the spacing between the primary electrode and counter-electrode during manufacture. Provides electrical insulation between the electrolyte within neighboring cells, while eliminating the need to provide a continuous source of e.g. a fiber-based insulating material for deposition on to the substrate. Ensures that a complex feed system for feeding fibers to the substrate need not be provided. Provides spacers that ensures that the primary electrode and counter-electrode of each cell are spaced apart by an appropriate distance.
