Abstract
Devices, methods, and systems are described for thick-film paste with multiple discrete frits. The paste may be applied to contacting crystalline silicon solar cell emitter surfaces. Each frit contains both lead and tellurium. The described multiple discrete frit paste has superior solar cell performance compared with single frit pastes made from the individual discrete frits that make-up the multiple frit paste.
