Reflection Spectra Simulation for Flat and Patterned Surfaces of CdTe Solar Elements

摘要

The paper comprises the simulation of light total reflection from solar element multilayered structure. For CdTe solar cell the analysis of optical losses in two different types of solar cells with indium tin oxide and zinc oxide as transparent upper contact (with glass superstrate and without it) is performed. The effect of glass superstrate in the elements is discussed and spectral dependences for reflectance in plain layer structure are built. For textured surfaces of solar element layer the comparison of influence of different types of texture on total light reflection is carried out.
