Passivated, hole-selective contacts play important role in reducing surface recombination by lowering the concentration of electrons in the rear side of a solar cell. However, parasitic optical losses in these contacts can still limit the performance of the cell. In this work, the long wavelength optical losses of silicon solar cells featuring hole-selective molybdenum oxide (MoOx) rear contacts are investigated using optical simulations. The potential of these selective contacts for possible enhancement of photogenerated current density was also investigated for their use with nanostructured dielectric layers.
