A C70-carbon nanotube complex for bulk heterojunction photovoltaic cells
A C70 fullerene-multi-walled carbon nanotube (C70-CNT) complex has been used as a
component of the photoactive layer in a bulk heterojunction photovoltaic cell. As compared
to a control device with only C70, the addition of CNTs led to improvements in short circuit
current density (J sc), open circuit voltage (V oc), and power conversion efficiency by 31.8,
17.5, and 69.5%, respectively. This device takes advantage of both the electron accepting
feature of C70 and the high electron transport capability of CNTs. These results indicate that …
