Abstract
The invention relates to glass compositions useful in conductive pastes for silicon semiconductor devices and photovoltaic cells. The thick film conductor compositions include one or more electrically functional powders and one or more glass frits dispersed in an organic medium. The thick film compositions may also include one or more additive(s). Exemplary additives may include metals, metal oxides or any compounds that can generate these metal oxides during firing.
