High-efficiency solar-cell arrays with integrated devices and methods for forming them

In various embodiments, an array of discrete solar cells with associated devices such as bypass diodes is formed over a single substrate. In one instance, a method of forming a solar-cell array with integrated bypass diodes comprising: providing a semiconductor substrate, a first cell comprising a SiGe p-n junction or SiGe p-i-n junction, one or more second cells each comprising a III-V semiconductor p-n junction or III-V semiconductor p-i-n junction; forming a bypass diode that is discrete and laterally separate from its associated solar cell and comprises an unremoved portion of the first cell, the formation comprising removing an unremoved portion of the one or more second cells thereover.
