20% output efficiency on 156mm wafer size with Roth&Rau's new
high-efficiency technology
Hohenstein-Ernstthal/Neuchâtel, 6 September 2011 - At this week's PVSEC
photovoltaics conference, Roth&Rau AG will be presenting the latest
development results achieved at the Roth&Rau research line and in its
pilot line. Since May 2008, the company has been developing high-efficiency
solar cells based on heterojunction technology. To this end, the company
agreed a cooperation with EPFL/IMT at the Universitéde Neuchâtel. Since
then, the two parties have worked together to transfer the results of the
Institute's research then available into industrial processes and to
systematically enhance these results. For the first time worldwide, the
research line at Roth&Rau Switzerland AG has achieved output efficiency
rates of 20% using 156mm industrial monocrystalline silicon wafers based on
heterojunction technology. The pilot line in Hohenstein-Ernstthal, where
the processes are already being scaled up for mass production systems, can
also point to superb results. These are due to be presented at the PVSEC
conference. 'The high level of output efficiency offered by heterojunction
technology, combined with its excellent temperature coefficients (>5%
additional energy yield per module), address the key cost factors in the
photovoltaics market. I am delighted that Roth&Rau has managed to bring
this technology from the research stage through to production maturity in
such a brief period', commented Dr. Dietmar Roth, CEO of Roth&Rau AG,
with regard to the current progress with the project.
Heterojunction technology is a technology already known of, but which has
to date only been put to industrial use by a single company. Heterojunction
cells are based on a low-temperature production concept. They are
characterised by superb passivation properties, leading to very high output
efficiency rates and excellent temperature behaviour. This high-efficiency
technology offers Roth&Rau' customers the possibility of achieving
substantial cost savings when investing in expanding their capacities, thus
securing Roth&Rau's market leadership in this attractive production
system segment.
