520 _ _ |a Tandem thin-film silicon solar cells consist of an amorphous silicon top cell and a microcrystalline silicon bottom cell which are stacked and connected in series. To match the photocurrents of the top cell and the bottom cell, a proper light management is essential. To this end, intermediate reflectors are applied between the top and the bottom solar cells. State-of-the-art single-layer intermediate reflectors are made of low refractive index materials but show poor spectral selectivity and cause parasitic reflection losses in the external quantum efficiency of the bottom cell. We report on the design of a multilayer intermediate reflector based on aluminum doped zinc oxide and microcrystalline silicon oxide with a spectrally selective reflectance. Rigorous optical simulations are used to examine the intermediate reflector even in textured thin-film solar cells. In a subsequent step, this intermediate reflector was successfully integrated into state-of-the art tandem solar cells deposited on a rough front contact. In agreement to simulation, an improved spectral selective reflectance of incident light is realized which increases the total charge carrier generation of the tandem solar cell by 0.7 mA/cm² in comparison to the state-of-the-art single-layer intermediate reflector.
