Inks for Ink Jet Printed Contacts for High Performance Silicon Solar Cells.

摘要

NREL developed dopant inks and pastes based on B, Al, P, and Sb. The inks were sprayed on Si wafers by BP Solar and NREL, and then laser processed by BP Solar to produce highly doped contacts. The higher viscosity pastes were screen printed by BP Solar, and then laser processed to produce highly doped contacts to Si wafers. At the completion of the CRADA, the project had produced Si wafer-based test cells with good conversion efficiencies using NREL-prepared dopant materials and laser processing.
