An optimum design of one dimensional photonic crystal for solar cell applications

Abstract Efficient anti reflection (AR) coatings and back reflectors are crucial components for the better performance of a solar cell. Hence perfect designing of the same is very important. We propose the design of both these structures based on a multilayer dielectric system, a one dimensional photonic crystal, with maximum efficiency on the basis of optical interference transfer matrix theory. Optical parameters were optimized and transmission and reflection spectra were obtained using transfer matrix formulation via a personal computer using MATLAB program. Theoretical analysis has shown that a triple layer AR coating and a DBR based back reflector effectively enhance the efficiency of a solar cell.
