We have demonstrated that the highest efficiency is obtained for the perovskite band gap of . The limiting efficiency in this case is slightly below 40%. Room for improvement of single-junction silicon solar cells is limited to around 3% (absolute).
Improving the efficiency of silicon-based solar cells beyond the 29% limit requires the use of tandem structures, which potentially have a much higher (~40%) efficiency limit. Both perovskite/silicon and III-V/silicon multijunctions are of great interest in this respect.
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.
Surprisingly, for silicon solar cells in the high-injection regime, the open-circuit voltage is found to be very sensitive to surface recombination when the cell thickness is smaller than a few tens of microns. This supports the conclusion that the optimal thickness for high-efficiency c-Si solar cells is above a few tens of micrometers [ 7 ].
At present, typical reported FF values for HJs are indeed in the range 82–83.5%, where the latter value is related to the actual record HJ cell with 25.1% efficiency. Martin Green obtained from an empirical expression a theoretical upper limit of 89% for silicon solar cells FF, only limited by Auger recombination.
The efficiency limits can be calculated by solving the transport equations in the assumption of optimal (Lambertian) light trapping, which can be achieved by inserting proper photonic structures in the solar cell architecture. The effects of extrinsic (bulk and surface) recombinations on the conversion efficiency are discussed.

This property can be used in the photovoltaic field to target different spectral ranges. III–V materials can absorb wavelengths ranging from mid-infrared to ultraviolet region. Superposition of III–V''s layers (multijunction) therefore allows to increase the spectral range absorbed by solar cells compared to silicon cells.

We have found that the limiting efficiency for cells in the thickness range between 40 and 500 μm is very similar and close to 29%. In this regard, we argue that decreasing the thickness below around 40 μm is counter-productive, as it significantly reduces the maximum achievable efficiency, even when an optimal light trapping is implemented.
