      Abstract:

      Superstrate a-Si:H solar cells incorporating a nano-column array   for light and photocarrier collection have been fabricated and   evaluated. It is found that the short circuit current density   (JSC) is significantly increased   while the open circuit voltage and fill factor are not   detrimentally affected by this architecture. Numerical analysis   of JSC matches experiment and   shows that the enhanced JSC  observed is due to both effective absorber thickness and   photonic-plasmonic effects. Further analysis shows that this   nano-column architecture can lead to a 42% increase in conversion   efficiency over that of the planar control for a 200 nm absorber   thickness cell.
