Trends in photoelectric conversion efficiency of crystalline silicon solar cells over the past few years. Subsequent developments also require lower costs reduced from material costs and processing costs. First, the thickness of the silicon wafer is reduced, i.e., the development of a thin silicon process.
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.
However, existing industrialized silicon solar cells exhibit simple structures. The single crystalline silicon with the Czochralski method or the polycrystalline silicon with the casting method has been adopted on a large scale. Generally, these silicon materials are boron diffusion doped, with a resistivity of 0.5–0.6 Ω cm.
