Abstract
This paper describes the development of an industrial process for increasing the efficiency of crystalline silicon solar cells by improving the front grid line conductivity without a concurrent increase in shading loss. The methodology to achieve this was to deposit silver (Ag) metal using light induced plating (LIP) onto a seed layer grid of conventional thick film screen printed Ag paste and apply this on an industrial scale. The feasibility of this technique had been previously reported on a laboratory scale with a cyanide based Ag electrolyte [1]. This paper details how this methodology was implemented in an industrial setting but using a non-cyanide Ag plating electrolyte and purpose built in line horizontal equipment. The capability of achieving efficiency gains typically between 0.2 - 0.4% absolute is shown.
