Reducing incident light reflection on silicon substrates (i.e., improving antireflectivity) to enhance solar power conversion efficiency is a crucial research goal. Generally, antireflective surfaces of monocrystalline solar cells are textured [ 4, 5] to reduce incident light reflection.
The typical loss of incident light from reflection from a silicon solar cell's front surface is 30%, which lowers the efficiency of the device's total power conversion (Wang et al., 2017). The reflection loss can be expressed as Equation 13. 5.2.2. Parasitic absorption
This texturing process thus reduces reflectance from 30 to 20%. Typically, solar cell surfaces are textured into V-shaped slots, right pyramids, or inverted pyramids. Passivated emitter rear locally diffused solar cell, developed by the University of New South Wales in the USA, exhibits a conversion rate of 24% [ 6, 7, 8, 9, 10 ].
In this article, using solar radiation in infrared (IR) wavelengths, a new technique is investigated to increase the efficiency of conventional solar cells.
A rear reflector is positioned after the absorber layer of a solar cell and is typically made of materials like ZnO/Ag or SiO2 /Ag. Its function is to reflect light that travels through the absorber layer and re-direct it into the cell (Kim et al., 2020).
5.1.3. Emission loss According to Kirchoff's law, materials that absorb light must also emit light, and this emission from the solar cell contributes to a decrease in conversion efficiency (Dupré et al., 2016). The loss of photons emitted by the cell due to radiative recombination is known as emission loss.
