In this paper, an analytical approach based on transmission line equivalent circuit (TLEC) is used to model planar solar cells. The proposed method has been applied to the all-dielectric planar solar cells with multilayer anti-reflection coating (ARC) and non-periodic distributed Bragg reflector (DBR) nanolayers. This analytical approach is very efficient and easy to be implemented. Consequently, it is straightforward to employ several optimization procedures to determine the optimum thickness for different layers. In this paper, optimization process according to the Fuzzy adaptive modified particle swarm optimization (FAMPSO) algorithm is utilized to maximize the absorption enhancement of these types of solar cells. Results demonstrate the possibility of wideband absorption in all-dielectric planar solar cells and comparable to the conventional light trapping structures.
