A theoretical simulation of light scattering of nanocrystalline films in photoelectrochemical solar cells

A Monte Carlo simulation method of light scattering in nanocrystalline film s based on solutions of Maxwell's equations is proposed. A nanocrystalline film is assumed to be superposition of randomly distributed nanoparticles a nd deviation of the nanocrystalline film from the randomness, Since a scatt ering field of the randomly and densely distributed nanoparticles can be ne glected, a scattering held of the nanocrystalline film results in a sum of scattering fields of the deviant parts in the nanocrystalline film. In the method, configurations of the deviant parts are simulated with a random fun ction of a computer language. A simulation converges in small number of the configuration patterns. The simulation theoretically demonstrates that alm ost all of the incident light to the nanocrystalline films in the photoelec trochemical solar cells penetrate without scattering.
