Abstract
Glass frits, conductive inks and articles having conductive inks applied thereto are described. According to one or more embodiments, glass frits with no intentionally added lead comprise TeO2 and one or more of Bi2O3, SiO2 and combinations thereof. One embodiment of the glass frit includes B2O3, and can further include ZnO, Al2O3 and/or combinations thereof. One embodiment provides for conductive inks which include a glass frit with no intentionally added lead and comprising TeO2 and one or more of Bi2O3, SiO2 and combinations thereof. Another embodiment includes articles with substrates such as semiconductors or glass sheets, having conductive inks disposed thereto, wherein the conductive ink includes glass frits having no intentionally added lead.
Claims21
A frit for a conductive ink for application to an anti-reflective coating on a semiconductor for use as a photovoltaic cell comprising:
- TeO2, B2O3, Bi2O3, and SiO2, the frit containing no intentionally-added lead, such that upon firing, the frit penetrates the anti-reflective coating to enable formation of ohmic contact between the conductive ink and the semiconductor.
