As c-Silicon solar cell becomes thinner, there is an increasing demand of non-contact printing process to avoid any damages during printing process. In addition, thinner front electrode lines are desirable for higher efficiency solar cells. Due to the above-mentioned reasons, inkjet printing process has become one of the candidates for next generation high efficiency c-silicon solar cells. Ag nanoparticle-based conductive ink was developed for the formation of electrode in c-Si solar cells and their sintering properties were studied. The ink, unlike the conventional Ag nano inks, includes Ag nanoparticles and nano-sized glass frits and show very unique electrode formation behaviors. In this report, we present the size-dependent behaviors of Ag nano inks for c-silicon solar cells.
