Heraeus Photovoltaics further expands its Intellectual Property portfolio

TAIPEI, TaiwanSept. 27, 2015 /PRNewswire/ -- Heraeus Photovoltaics, the worldwide leading supplier of metallization pastes to the PV industry, has acquired three patent families from the Japanese company Murata Manufacturing. The patent families on the basis of the international patent applications WO2014050703, WO2014045900 and WO2014050704 refer to metallization pastes, which contain glass compounds (glass frit) with specific material combinations basing on Tellurium-Oxide. The patents further strengthen the company's intellectual property position as the market leader in the development, manufacturing and use of pastes having tellurium containing glass frit in the paste compositions.
Glass frit is a key component in the formulation of metallization pastes, enabling the electrical contact formation between the silicon substrate and the metal electrode. Tellurium containing pastes have demonstrated improved electrical contact to silicon solar cells over non tellurium containing paste. Furthermore, Tellurium containing glasses play an important role in lead-free pastes, which is increasingly gain market share due to environmental considerations.
