A primer to the photovoltaic effect in semiconductors The operation of solar cells is based on the photovoltaic effect that is the direct conversion of incident light into electricity by a p – n (or p – i – n) junction semiconductor device.
The power conversion efficiency of single-junction solar cells is governed by the thermodynamical Shockley–Queisser limit of ∼31% for unconcentrated solar light .
Photovoltaic (PV) conversion of solar energy starts to give an appreciable contribution to power generation in many countries, with more than 90% of the global PV market relying on solar cells based on crystalline silicon (c-Si). The current efficiency record of c-Si solar cells is 26.7%, against an intrinsic limit of ~29%.
In 1893 the photovoltaic effect was reported leading to actual photovoltaic solar cells (PVScs) that can produce electricity from solar radiation taking into consideration the Schockly-Queisser efficiency limitations.
The world PV market is largely dominated (above 90%) by wafer-based silicon solar cells, due to several factors: silicon has a bandgap within the optimal range for efficient PV conversion, it is the second most abundant material on the earth’s crust, it is nontoxic and its technology is well mastered by chemical and semiconductor industries.
Future developments of thin-film c-Si solar cells will depend on progress in the material processes for the preparation of non-wafer-based silicon (layer transfer, liquid-phase recrystallization, and the like). 4. Efficiency limits with Lambertian light trapping
