Abstract

High-performance broad-spectrum nanocarbon bulk-heterojunction photovoltaic photodetectors are reported. These reported photodetectors consist of a semiconducting single-walled carbon nanotube (s-SWCNT) and a PC71BM blended active layer. Magnetic-field effects and the chirality of the s-SWCNTs play an important role in controlling the photoresponse time and photocurrent improvement.
