Advanced Solar-Grade Si Material

Abstract

Silicon-based technologies account for more than 90% of global PV installations. Since decades, scientists around the world have been searching for the right technology to produce silicon feedstock for the photovoltaic industry, which fulfils the needs for “low cost” as well as the needs for sufficient quality. The urgency of this task has intensified since 1998, when it became clear that the PV demand could no longer be met with by-products from the electronic industry.
