Abstract
Optical modelling is used to investigate the potential improvements in quantum efficiency and short-circuit current density of the top and bottom silicon cell in tandem micromorph configuration. The effects of enhanced haze parameter and different angular distribution functions of scattered light are presented and analysed. The role of an intermediate reflector (interlayer), located between the top and bottom cell, is studied from the optical point of view. The improvements in quantum efficiency of top cell are demonstrated for different types of interlayers. Potential thickness reductions due to enhanced light trapping in the solar cells are presented.
