Problem
Current printed electronics rely predominantly on p-type conductive inks, which transport positive charges. The absence of high-performing and stable n-type (negative charge transporting) inks limits the efficiency and performance of various electronic devices, hindering the development of complementary metal-oxide-semiconductor (CMOS)-like technology in printed electronics.
Solution
N-Ink develops and patents n-type conductive polymer inks designed to enhance the performance and sustainability of printed electronics. These inks offer high electron conductivity and thermal stability, addressing the limitations of existing materials in energy storage, solar cells, and electric vehicle components. N-Ink's materials are formulated to be eco-friendly, utilizing water, alcohol, or DMSO-based solutions, and are designed to comply with upcoming regulations restricting the use of per- and polyfluoroalkyl substances (PFAS). The inks are compatible with large-scale deposition methods, including inkjet printing, and are orthogonal to most organic solvents, enabling overprinting and multilayer device fabrication.
Target Audience
N-Ink's primary customers include manufacturers of energy storage systems, solar cells, electric vehicle components, and other printed electronic devices seeking to improve performance and sustainability.
