Tokyo, Japan, May 15, 2014 --- The Teijin Group announced today that it will participate in SNEC PV POWER EXPO 2014, one of the world's largest trade shows focusing on photovoltaic (PV) power, which will take place at the Shanghai New International Expo Center, China from May 20 to 22.

The Teijin Group booth (No. W4－811) will present a cutting-edge electronic material under development, named "NanoGram Si (silicon) ink/paste" for PV cells. The exhibit will showcase the material's superior properties as well as the Teijin Group's advanced solutions for high-efficiency PV cells.

NanoGram Si ink/paste is a printable diffusing dopants incorporating the technologies of nanoparticle manufacturing and dispersion. Teijin's advanced dopants, which contain silicon particles with diameter of several tens of nanometers, can form thin and thick layer on a silicon substrate. It is suitable for printed electronics applications using ink-jet and screen printing technology since this product has stable property without any dispersing agents.

The silicon nanoparticles contain high concentration of phosphorus and boron. This property enables the laser doping process as well as the thermal diffusion, resulting in high efficiency and simplifying manufacturing process of silicon-crystal PV cells.

NanoGram Si ink/paste is being developed by NanoGram Corporation, a Teijin Group company specialized in novel nanomaterials design technology. This company researches, develops and produces ink/paste products especially for electronics applications in Silicon Valley, California.
