Abstract (en)

[origin: WO7900813A1] Improvements in shallow-homojunction solar cells based upon a plurality of layers of a direct gap semi conductor material such as GaAs, as well as their fabrication, are disclosed. The shallow-homojunction solar cells have a n+/p/p+ structure (26, 24, 22) in which the n+ top layer (26) is limited to a thickness which permits significant carrier generation to occur in a lower semiconductor layer (24). An antireflection coating (28) is applied over the n+ top layer (26), and a particularly preferred method for applying the antireflection coating is by anodization. These solar cells can be grown on relatively inexpensive substrates, if desired, such as silicon or germanium.
