Abstract: Carrier generation is one of the important processes in solar cell operations. The generation rate depends on the number of photons absorbed by solar cell. This absorption of photons is affected by the reflection losses. The light trapping technique is used to minimize the reflection loss. In this work, a theoretical design of Effective Interface Antireflective Coating (EI-ARC) in solar cell is proposed which is based on the theory of Fabry–Perot interference filters. This design is composed of a space index layer with two subsystems of multilayer, which allows multiple reflections within it. It is shown that the combination of this two systems yields high transmission values over a narrow spectral range. This EI-ARC model increases the Internal Quantum Efficiency (IQE) and carrier generation rate of solar cell. These parameters are significant to raise the efficiency of the solar cell.
