Schematic diagram of crystalline silicon solar cells. For ideal solar cells, four main assumptions are proposed: there exists no transport loss, and the body recombination is minimal. Under the mentioned assumptions, the minimum Auger recombination and good free carrier collection can be obtained with the intrinsic substrate material.
Crystalline silicon is the most important material for solar cells. However, a common problem is the high RI of doped silicon and more than 30% of incident light is reflected back from the surface of crystalline silicon .
A typical real silicon solar cell cross-section. The material used to fabricate a solar cell, which is the base, is always p-doped. The n-doped region is called the emitter side. Photocurrents in a real solar cell: Light is believed to enter on the emitter side for the measurement of photocurrents.
