HIGH EFFICIENCY SINGLE CRYSTAL SILICON SOLAR CELL WITH EPITAXIALLY DEPOSITED SILICON LAYERS WITH DEEP JUNCTION(S)
Embodiments of the present invention may include single crystal silicon solar cell structures with epitaxially deposited silicon device layers with deep junction(s). In some embodiments, the single crystal silicon solar cell structures may comprise a moderately doped, thick (greater than 10 microns), epitaxially deposited silicon emitter layer. In some embodiments, the single crystal silicon solar cell structures may comprise moderately doped, thick (greater than 10 microns), epitaxially deposited FSF layers. The moderate doping reduces electron-hole recombination within the FSF and emitter layers and causes smaller bandgap narrowing and reduced Auger recombination compared to prior art devices which typically have more heavily doped layers, and the thicker FSF and emitter layers than typically used in prior art devices assist in having a desirable sheet resistance for the solar cell front and back surface, as measured prior to front side and back side metallization.

Embodiments generally relate to optoelectronic devices and more specifically, to textured layers in optoelectronic devices. In one embodiment, a method for providing a textured layer in an optoelectronic device includes depositing a first layer of a first material and depositing an island layer of a second material on the first layer. Depositing the island layer includes forming one or more islands of the second material to provide at least one textured surface of the island layer, where the textured surface is operative to cause scattering of light.
