Fig.14. Demonstration of all-carbon nanotube photovoltaic effect: a) The edge of the SWNT film observed under SEM, and b) SEM image of this film showing SWNT network. c) Schematic view of the contact formation between two SWNT films: Yellow stars symbolize the junctions between bundles, (1)–(3) represent three different inclination angles. d) I–V characteristics at “first touch” conditions: under dark and light illumination.
