S. Del Gobbo, P. Castrucci, M. Scarselli, L. Camilli, M. De Crescenzi et al. Different amounts of single wall carbon nanotubes (SWCNTs) have been sprayed on amorphous silicon substrates to form Schottky barrier solar cells. The measured external quantum efficiency showed a spectral behavior depending on the SWCNT network optical transparency, presenting a maximum up to 35% a ... [Appl. Phys.
