The paper describes an efficient implementation of a photoabsorption model for modern thin photovoltaic (PV) cells. As the modelling of solar cells constitutes a multiphysic and multiscale problem, a special attention was paid to the speed while retaining a reasonable accuracy. The model is restrained to a normal incidence but accounts for the whole solar spectrum. Applied transfer matrix method yields an accurate distribution of the light intensity in the semiconductor structure. Usage of equivalent parameters makes it possible to simulate both plain semiconductor material and a quantum dot superlattice based material, which is used to enhance the PV device performance.
