Abstract
We are developing inkjet printing as a low cost, high through-put approach to the deposition of front contacts for Si solar cells. High deposition rates of 1?m per printing pass were achieved with a new metalorganic ink composed of silver (trifluoroacetate) in ethylene glycol. The printing conditions were optimized to achieve a relatively high line resolution of 120 ?m. The optimal parameters forthe piezoelectric inkjet were a pulse frequency of 50 Hz and pulse amplitude of 25 V. The best resolution and the line quality were achieved at a substrate temperature of 180 ?C and drop separation of 40 ?m.
