Abstract:
This study focuses on enhancing the charge
transport in hybrid TiO2/ P3HT solar cells by incorporating
Multi Wall Carbon Nanotube (MWCNT) within the
nanoporous TiO2 electron transporting layer. We systematically
changed the weight ratio of MWCNTs which was blended with
TiO2 nanoparticles and studied the effect caused in hole mobility using Time of Flight technique. We found two orders
of magnitude increase in hole-mobility while adding 0.02wt %
MWCNT into porous TiO2. This is consistent with the
corresponding current-voltage characteristics of above solar
cells.
