This paper reports ink-jetted gridline, production ready, solar cells with ion implanted homogeneous high sheet resistance emitters having efficiency of >19%. The average efficiency of ∼18.96% on 80 ohm/square ion implanted emitter with highest efficiency of 19.2% demonstrates the potential of combining the two high precision technologies, inkjet printing and ion implantation. The key attributes of the cells include average open circuit voltage (VOC) of 640mV, fill factor (FF) of 79.14% and short circuit current density (JSC) of 37.8mA/cm2. Worthy of note is that, the front gridlines width and height of 47.6μm and 43.9μm resulting in aspect ratio of 0.92 using only 83mg total Ag, which is, at least 20% Ag less than today's screen printed cells. However, the reference screen-printed cells showed similar average efficiency with the best gridline widths of ∼70μm and height of ∼28μm used >100mg of Ag. Statistical analysis illustrates that the highest efficiency with the screen-printed contacts is an outlier as the minimum efficiency for the ink-jetted group. This efficiency is very significant because all cells were fabricated on a pilot production line at Shanghai Shengzhou New Energy Co. Ltd, in China.
