摘要:
A conductive paste composition contains a source of an electrically conductive metal, a lead-tellurium-based oxide, and an organic vehicle. An article such as a high-efficiency photovoltaic cell is formed by a process of deposition of the lead-free paste composition on a semiconductor substrate (e.g., by screen printing) and firing the paste to remove the organic vehicle and sinter the metal and lead-tellurium-based oxide.
摘要:
The present invention is directed to an electroconductive thick film paste composition comprising Ag and a Ph-free Bi-based glass frit both dispersed in an organic medium, wherein the paste is fireable at temperatures below 420° C. The paste is especially useful for forming electrodes on substrates such as glass or films, particularly electrochromic glass or films, that would be damaged by higher firing temperatures. The present invention is further directed to a device comprising an electrode formed from the paste composition and, in particular, to an electrochromic device comprising such an electrode.
