Does thickness of antireflecting material affect solar cell performance?

Furthermore, the paper has worked on the role of thickness of the antireflecting material on the performance of the solar cell. It is found that ZnO material with thickness has shown higher at wavelength (532.4nm) and (774.4nm).

How thick is slarc coating?

As it can be seen for SLARC, all the coatings have a thickness of under 80 nanometers with the exception of SiO 2 coating that is 173 nm thick. The reflection and absorption plots of SLARC are shown in Fig. 2 (a) and Fig. 2 (b) respectively.

What is the most common coating used on silicon solar cells?

The most common coating of this group is Si 3 N 4 which is the most common coating used on silicon solar cells. This coating can discourage carrier recombination and act as an oxygen barrier, dielectric, and adhesion layer , , .

Which coating thickness is required to achieve reflectance minima?

In the case of SiO 2, a coating thickness of 70 nm yields reflectance minima of 0.14. In the case of Si 3 N 4, between 70–80 nm of coating thickness is required to achieve reflectance minima closer to near 600 nm. 80 to 90 nm thick Al 2 O 3 -based coating thickness is necessary to attain reflectance minima.

Do antireflecting-layers index and wavelength affect the performance of solar cells?

The selection of antireflecting-layers index and wavelength are related to better Power Conversion Efficiency (PCE) and reduced reflection of solar cell. However, an improvement in the performance further demands an additional reflective layer coating, thus making fabrication an expensive process.

How to model optical properties of antireflection coatings on silicon?

Optical properties of antireflection coatings on silicon can be modelled by either using Transfer matrix theory modelling , Airy’s expression, Differential Evolution (DE) algorithm , Multi-rad , Dupoisot & Morizet, method , etc.
