title: Transport behaviors of photo-carriers across the aligned carbon nanotubes and silicon interface.
abstract: Transport of photo-carriers across the aligned carbon nanotubes and silicon (CNT/Si) interface determines cell performance. It is revealed that S-shaped current-voltage characters are generated due to the mismatch between the generation and transportation of photo-carriers, which can be eliminated by tuning the light intensity and CNT coverage on the Si surface, with the power conversion efficiency enhanced up to 121%.
