NOVELTY - Solar-cell array (100) with integrated bypass diodes (1450) comprises: a substrate; disposed over the substrate, many discrete solar cells (1440) electrically connected in series to form a series string of discrete solar cells for supplying, under solar illumination, a voltage larger than a voltage produced by any of the discrete solar cells individually; and disposed over the substrate, many bypass diodes, each associated with a different discrete solar cell, and being discrete and laterally separate from its associated solar cell.    USE - The solar cell array is useful in solar panels.    ADVANTAGE - The solar-cell array: is highly efficient; can be manufactured with silicon-dedicated facilities, having computational simplicity and requires fewer sense inputs; is less prone to instability; exhibits improved current state; and remains continuously connected to the load without significant disruption.    DETAILED DESCRIPTION - Solar-cell array (100) with integrated bypass diodes (1450) comprises: a substrate; disposed over the substrate, many discrete solar cells (1440) electrically connected in series to form a series string of discrete solar cells for supplying, under solar illumination, a voltage larger than a voltage produced by any of the discrete solar cells individually, where each of the discrete solar cells comprises a first cell comprising a silicon germanium p-n junction, a silicon germanium p-i-n junction, a III-V-semiconductor p-n junction, or a III-V-semiconductor p-i-n junction, and disposed over the first cell, at least one second cell each comprising a III-V-semiconductor p-n junction or a III-V-semiconductor p-i-n junction; and disposed over the substrate, many bypass diodes, each associated with a different discrete solar cell, being discrete and laterally separate from its associated solar cell, and comprising at least a portion of the first cell without the second cells over it, where a distance between the substrate and the at least a portion of the first cell of the bypass diode is equal to a distance between the substrate and the first cell of the solar cell associated with the bypass diode, and each bypass diode is electrically connected with its associated solar cell so that the bypass diode and the discrete solar cell have opposite polarities.
