Polyalkylene carbonate binders for cleaner burning thick film Ag paste: Comparison to commercially available Ag pastes

Use of clean-burning binder systems in thick film paste formulations for solar cell applications offer advantages of reduced residual carbon, improved conductive feature density, and overall performance and reliability. This paper presents the technical advantages of employing clean-burning polyalkylene carbonates (QPAC
^®
) as the principle binder for thick film Ag paste. Rheological, thermal, structural, and electrical characteristics are presented and compared with commercially available Ag pastes.
