© 2016 Elsevier B.V. We present a simple fabrication process of heterojunction solar cells from single-walled carbon nanotubes (SWCNTs) and n-type silicon wafer. SWCNTs were synthesized from alcohol-catalytic chemical vapor deposition and were made into a film with transmittance of 70% by vacuum filtration. The mean diameter of the nanotube was about 1.1 nm. The patterned silicon substrate was prepared by a simple wet-etching process with hydrofuric acid utilizing a hand-made physical mask. The nanotube film was transferred onto the patterned silicon substrate. Power-conversion efficiency value of 4.3% with fill factor of 0.67 can be achieved. Abstract code: BO21.
