Optical reflection loss is a crucial factor restricting the efficiency improvement of solar cells. This paper briefly introduces the transfer matrix method in optical thin films, which is the basic method and principle of designing single, double, and multiple layer ARCs.
However, one of the major bottlenecks limiting the efficiency of solar cells is the light loss due to surface reflection, inadequate transparency, and spectral mismatch, which accounts for nearly 7% of the decrease in solar cell efficiency , and the heat loss caused by high-energy charge carriers in the short wavelength range .
Efficiency losses in the solar cell result from parasitic absorption, in which absorbed light does not help produce charge carriers. Addressing and reducing parasitic absorption is necessary to increase the overall efficiency and performance of solar cells (Werner et al., 2016a).
