Abstract :
Optical modeling and results of numerical simulation of thin-film Cu(In,Ga)Se2 solar cells are presented. Main features of the developed optical simulator SunShine are explained. An approach to model light scattering at rough interfaces in the solar cell is described. Two types of scattering parameters are used: haze and angular distribution function of scattered light. Simulation results - total reflectance, absorptance in CIGS absorber and carrier generation rate profile - are shown and verified for the solar cell with thin (d=360 nm) CIGS absorber
