For silicon solar cells, the basic design constraints on surface reflection, carrier collection, recombination and parasitic resistances result in an optimum device of about 25% theoretical efficiency. A schematic of such an optimum device using a traditional geometry is shown below.
Crystalline silicon solar cells generate approximately 35 mA/cm2 of current, and voltage 550 mV. Its efficiency is above 25 %. Amorphous silicon solar cells generate 15 mA/cm2 density of current and the voltage without connected load is above 800 mV. The efficiency is between 6 and 8% (S. W. Glunz et al. 2006).
However, silicon's abundance, and its domination of the semiconductor manufacturing industry has made it difficult for other materials to compete. An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick.
As is also the case for transistors, silicon does not have optimum material parameters. In particular, silicon's band gap is slightly too low for an optimum solar cell and since silicon is an indirect material, it has a low absorption co-efficient.
Basic schematic of a silicon solar cell. The top layer is referred to as the emitter and the bulk material is referred to as the base. Bulk crystalline silicon dominates the current photovoltaic market, in part due to the prominence of silicon in the integrated circuit market.
Two basic design parameters are the band gap of the top cell and the thickness of the silicon wafer for the bottom cell, which are related. To unravel and quantify this intricate relationship, first, we use our simulation platform for the STC, and then, we run it for the whole globe.
