However, this trend of high efficiency for single crystal-based solar cells is not observed in PSCs, as depicted in Fig. 1 c. The graph shows that SC-PSCs cannot achieve a higher efficiency than PC-PSCs. This may be attributed to the limited research on SC-PSC, as indicated by the number of published research articles for both SC-PSC and PC-PSC, as
The single crystal silicon synthesized by these methods has good linearity and can be effectively regulated in size, but it is not suitable for preparing silicon wires in a large area, which is also a problem to be solved in the future development of photonic crystal solar cells.

See all authors Single junction crystalline silicon (c-Si) solar cells are reaching their practical efficiency limit whereas perovskite/c-Si tandem solar cells have achieved efficiencies above the theoretical limit of single junction c-Si solar cells.
The one sun record efficiencies for solar cells based on a single Si absorber have remained unchanged 2 in the last ∼3 years at 26.7% [2, 3] for c-Si cells with passivating contacts based on SHJ and at 26.1% for passivating contacts based on polycrystalline Si on oxide (POLO) junctions .
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%.
During recent years, a lot of effort has been taken to achieve the very limits for single junction silicon solar cells experimentally. The highest efficiencies reported so far are 26.7% for n-type and 26.1% for p-type [ 5] silicon solar cells.
