Crystalline silicon solar cells are the most widely used solar cells, which have intrinsic limitation on the theoretical conversion efficiency (33.7% based on Shockley and Queisser's analysis) , and the actual conversion efficiency of crystalline silicon solar cells is as low as 20%.
Solar cells made from multi-crystalline silicon will have efficiencies up to ~22%, while 25% single junction monocrystalline silicon solar cells have been made from electronic grade silicon. Above 1414 °C, silicon is liquid. While crystalline silicon is semiconducting, liquid silicon is metallic and very reactive with air.
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 .
Therefore, the optical properties of silicon are isotropic. At room temperature, photons greater than ~1.05 eV are absorbed; according to the Shockley-Queisser limit the maximum possible efficiency of a single-junction silicon solar cell is ~31.5%.
However, there is a physical limit depending on the number of junctions and the material properties that bounds the maximum achievable efficiency. The current industry is built upon single-junction crystalline silicon cells, as silicon is the second most abundant material on Earth, and it is non-toxic.
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.
