NOVELTY - The photovoltaic module comprises a transparent substrate, and series-connected ten solar cells attached to the transparent substrate. An area of two of the solar cells differs from each other by 5% relative to an average area. The difference in area of the cells results in a better match of current output of the individual cells relative to cells of equal area with the same respective photo-conversion efficiency as the particular cells of the module.    USE - Used as photovoltaic module.    ADVANTAGE - The photovoltaic modules can produce higher power relative to modules with similar equal sized cells in economical manner, and is capable to improve the ability of the module performance with different size structures of the solar cells with high efficiency.    DETAILED DESCRIPTION - The photovoltaic module comprises a transparent substrate, and series-connected ten solar cells attached to the transparent substrate. An area of two of the solar cells differs from each other by 5% relative to an average area. The difference in area of the cells results in a better match of current output of the individual cells relative to cells of equal area with the same respective photo-conversion efficiency as the particular cells of the module. The solar cells comprise a silicon/germanium layer having an average thickness form of 5-100 microns. The current output of the cells under uniform illumination with sunlight differs from each other by no more than 5 percent. INDEPENDENT CLAIMS are included for:    (1) a solar cell; and    (2) a method for subdividing a semiconductor sheet for use as individual photovoltaic cells within a photovoltaic module.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic side perspective view of a photovoltaic module with a portion of the backing layer removed to expose some of the solar cells within the module.
