Abstract: CSG Solar’s device fabrication sequence involves both n-type and p-type contact patterning processes. The placement accuracy and feature size resulting when these patterning processes are performed using an inkjet printhead strongly influences the final performance of the photovoltaic device. CSG Solar worked with an inkjet printhead manufacturer to develop a printhead able to deliver improved feature size and placement accuracy. CSG Solar also undertook efforts to develop and test a new ink that would be matched to this new printhead. Using this new ink and printhead to perform its patterning processes, CSG Solar has been able to match previously reported efficiencies that were achieved using its original research-scale patterning approach. This paper describes the procedure undertaken to develop, test and appraise a new inkjet ink. The improvement in photovoltaic conversion efficiency resulting from the use of this new ink and printhead is also presented.
