SouthWest NanoTechnologies Introduces Nanotube-Based PV Screenprinting Inks

SouthWest NanoTechnologies Inc. (SWeNT), a provider of single-wall and specialty multi-wall carbon nanotubes (CNT), has developed a new family of conductive and semi-conductive CNT inks for several applications, including photovoltaics.

SWeNT CNT inks are based on V2V technology developed by alliance partner Chasm Technologies Inc. Using single-wall CNTs, these inks can be printed using commercial, high-volume printing methods and equipment.

The process eliminates the need for subtractive patterning, as well as post-production processes needed to remove ink dispersants and surfactants that are present with other printable CNT inks and that degrade optoelectronic performance, the company says. Combined with SweNT's unique ability to tailor the synthesis of CNT materials for applications (using its patented process), customers are able to print large-area, low-cost devices for a wide range of applications, according to the company.
