In the paper the developed two-dimensional optical model for the analysis of optical properties of thin-film solar cells with periodic textures (diffraction gratings) is presented briefly. The model is then used for the analysis of the potential of diffraction gratings as a back metal reflectors and scatterers in thin-film microcrystalline solar cells. The effects of enhanced scattering are analysed for the two types of gratings: rectangular-like and triangular-like. Optical losses related to surface plasmon effects at periodically textured metal back reflector (Ag) are investigated.

Two advanced optical concepts in thin-film solar cells are investigated: diffraction gratings and photonic crystals. For diffraction gratings the simulator FEMOS 2D is used to analyse the effects of light scattering and antireflective effect related to gratings. Photonic crystals are designed and investigated by means of the optical module for photonic crystals and SunShine simulator. Potential improvements related to photonic crystal back reflectors are analysed for amorphous Si based solar cells. Results of simulations are verified with measured data of the fabricated samples.
