The printing of conductive grids on solar cells to enhance current collection is<br />

well established in photovoltaic technology. The grid design, the dimensions of<br />

the lines and the busbar are optimised to minimise resistive and shadowing<br />

losses. The simplicity and the high throughput of screen printing makes it the<br />

current state of art metallization technique. However, the minimum achievable<br />

line width limits further reduction of the shadowing losses. ElectroStatic JET<br />

(ESJET) is a novel deposition technique which allows printing of ultra-fine<br />

conductive lines (<br />
