IN-CELL BYPASS DIODE

Abstract:

A solar cell can include a built-in bypass diode. In one embodiment, the solar cell can include an active region disposed in or above a first portion of a substrate and a bypass diode disposed in or above a second portion of the substrate. The first and second portions of the substrate can be physically separated with a groove. A metallization structure can couple the active region to the bypass diode.
