NOVELTY - An electronic substrate comprises a base (102) (particularly a printed circuit board or a hybrid microcircuit) that provides path options; conductive pad(s) formed over the base such that pad spaces are created between adjacent conductive pads, receives photovoltaic strip(s), and electrically connects with the path option(s); and bond pad(s) over the base, which provides an interface to connect the photovoltaic strips (902) to the path options in a predefined manner.    USE - Electronic substrate for photovoltaic module.    ADVANTAGE - The electronic substrate provides photovoltaic module with high rigidity, lesser weight by using a lesser amount of material, suitable for mass manufacturing, and costs low.    DETAILED DESCRIPTION - An electronic substrate comprises a base (102) (particularly a printed circuit board or a hybrid microcircuit) that provides path options; conductive pad(s) formed over the base such that pad spaces are created between adjacent conductive pads, receives photovoltaic strip(s), and electrically connects with the path option(s); bond pad(s) formed over the base, which provide an interface to connect the photovoltaic strips (902) to the path options in a predefined manner (series and/or parallel arrangement); and concentrating element(s) (906) for concentrating solar energy over the photovoltaic strips. The pad spaces receive optical vees (904) for concentrating solar energy over the photovoltaic strips. The optical vees comprise a reflective layer or surface, such that rays incident on the reflective layer or surface are reflected towards the photovoltaic strips. The refractive indices of the concentrating element and the optical vees are more than the refractive index of air or vacuum. INDEPENDENT CLAIMS are included for:    (1) a photovoltaic module for generating electricity from solar energy, comprising an electronic substrate and connector(s) for connecting the photovoltaic strips to the bond pads; and    (2) an apparatus for generating electricity from solar energy.    DESCRIPTION OF DRAWING(S) - The drawing is a blow-up view illustrating a photovoltaic module.    Base (102)    Photovoltaic strips (902)    Optical vees (904)    Concentrating elements (906)
