Using only 3–20 μm -thick silicon, resulting in low bulk-recombination loss, our silicon solar cells are projected to achieve up to 31% conversion efficiency, using realistic values of surface recombination, Auger recombination and overall carrier lifetime.
The theoretical limiting efficiency of the crystalline silicon solar cell under non-concentrating sunlight is about 29% . This is not far below the theoretical limit for any single junction solar cell.
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%.
Turning to the results, the conversion efficiency of c-Si solar cells has a maximum at a given value of the thickness, which is in the range 10–80 µm for typical parameters of non-wafer-based silicon.
According to this modern version of the SQ limit, the maximum theoretical efficiency of solar cells made of crystalline (amorphous) Si is η ∼ 33 % (∼28 %) that, nowadays, corresponds to the most accepted value.
It is from 1954 the first estimate of the maximum efficiency (around 22 %) a Si solar cell can exhibit, and it was made by the same scientists that invented the device (Chapin et al., 1954).
