Abstract
A thin silicon solar cell is described. An example solar cell may be fabricated from a crystalline silicon wafer having a thickness of approximately 50 micrometers to 500 micrometers. The solar cell comprises a first region having a p-n homojunction, a second region that creates heterojunction surface passivation, and a third region that creates heterojunction surface passivation. Amorphous silicon layers are deposited on both sides of the silicon wafer. A final layer of transparent conductive oxide is formed on both sides. Metal contacts are applied to the transparent conductive oxide.
