Abstract
A multijunction solar cell including a substrate and at least one solar subcell having an emitter layer, a base layer, and a window layer adjacent to the emitter layer composed of a semiconductor window material, wherein the window material has a graded composition such that the material at the interface between the top surface of the emitter layer of the at least one solar subcell and the bottom surface of the window layer has a compression as measured by a delta in the Bragg angle from the substrate in a range of 0 to 500 arcseconds in compression, and material at the top surface of the window layer has a tension as measured by a delta in the Bragg angle from the substrate in a range of 50 to 700 arcseconds in tension, wherein the delta in the Bragg angle is obtained from a rocking curve from a triple axis coupled scan of Ω and 2θ (omega-2theta) using 1.5406 Å radiation.
