“…It is clear that carbon nanotube films function, at least, as transparent conducting front electrodes. Carbon nanotube films have been used similarly in amorphous silicon solar cells [ 11 , 22 ], heterojunction solar cells of quantum dots and silicon [ 23 , 24 ], on silicon nanowires with [ 25 ] and without [ 26 , 27 ] photoactive polymers, as well as enhancing the performance of “standard” p - n junction silicon solar cells [ 28 ]. Photovoltaic output from SWCNT-silicon cells can be improved by the addition of graphene “patches” to the nanotube film [ 29 ] and by flowing gasses over the surface of the nanotube film, an effect that has been used to fabricate gas sensors [ 30 ].…”

The results of measurements on solar cells made from randomly aligned thin films of single walled carbon nanotubes (SWCNTs) on n-type monocrystalline silicon are presented. The films are made by vacuum filtration from aqueous TritonX-100 suspensions of large diameter arc-discharge SWCNTs. The dependence of the solar cell performance on the thickness of the SWCNT film is shown in detail, as is the variation in performance due to doping of the SWCNT film with SOCl2.

The possibility of preparing straight multiwalled carbon nanotubes (MWCNTs) on a large scale is demonstrated using direct current arc discharge with a rotating graphite anode in low pressure air. The process is time-saving, economical, and non-hazardous. It is found that the optimum air pressure for the highest yield of MWCNTs is about 60 Torr. Investigation of the internal organization of the cathode deposit reveals that many columns about 40 lm in diameter are closely packed and mechanically stable. The highest content of MWCNTs is found in the intercolumnar spaces between columns. Emitters made of the cathode deposits that contain a large number of straight nanotubes exhibit outstanding field emission properties. The turn-on electric field decreases from 1.44 to 0.93 V/lm and the field enhancement factor b increases from about 3,190 to 7,830 only after simple burning at 750°C for 30 min in air. The results indicate that MWCNTs prepared by arc discharge in air are promising for field emission application.

“…The 1D nanoscale structure, high mobility, and excellent mechanical, electrical properties, as well as environmental stability [5,6] of carbon nanotubes (CNTs) offer great promise in the development of high-efficiency solar cells [7,8]. CNTs have been embedded in polymer matrix [9] or other semiconductors [10] and as transparent electrodes [11], facilitate the separation, transport and collecting of charge carriers. Recently, that CNTs and silicon can form heterojunctions [12] in solar cells has become a hot topic.…”
