Abstract:
1. A solar cell comprising: a sliver of a silicon wafer, the sliver having a front side and a back side, the front side of the sliver being configured to face towards the sun during normal operation, the back side of the sliver being opposite the front side of the sliver, the front side of the sliver comprising a surface from along a thickness of the silicon wafer rather than along a plane of the silicon wafer; a first doped region configured as a base of the solar cell; a second doped region configured as an emitter of the solar cell; and a first metal contact and a second metal contact formed on the back side of the sliver, the first metal contact being electrically coupled to the first doped region, the second metal contact being electrically coupled to the second doped region.
