PROJECT TITLE :

High-Efficiency n-Type Si Solar Cells With Novel Inkjet-Printed Boron Emitters

ABSTRACT:

Formation of a well-passivated boron emitter for mass production of low-cost and high-efficiency n-type silicon solar cells is a major challenge in the photovoltaic industry. In this letter, we report on a novel and commercially viable method, inkjet printing, to create boron emitters. Phosphorus diffusion was used on the rear to form a back-surface field in conjunction with chemically grown oxide/silicon nitride $(hbox{SiN}_{x})$ stack on the front and back for surface passivation. Finally, front and back screen-printed contacts were formed through the dielectric stacks to fabricate large-area (239 $hbox{cm}^{2}$) n-type cells. This technology resulted in 19.0%-efficient p$^{+}$-n-n $^{+}$ cells with a $V_{rm oc}$ of 644 mV, a $J_{rm sc}$ of 38.6 $ hbox{mA/cm}^{2}$, and a fill factor of 76.3%. This demonstrates for the first time the promise of boron-inkjet-printing technology for low-cost and high-performance n-type Si cells.
