BURNABY, BC, Sept. 7, 2011 /CNW/ - Day4 Energy Inc., a leading global
provider of solar photovoltaic (PV) products and solutions and Roth &
Rau (R&R), a world leader in mass production equipment for solar cell
production announce that a first module with an efficiency of 19.3%
(cell area) has been produced. The new cells and PV modules utilize
R&R's Heterojunction Technology and Day4's DNA Technologies.
Roth & Rau has already announced the latest results of Heterojunction
Technology at the cell level at the current 26th European Photovoltaic
Solar Energy Conference. Heterojunction Technology offers superior
passivation properties compared to standard cell processing
technologies, leading to high efficiency and very favorable temperature
behaviour. Moreover, the production process has very few production
steps and is fully compatible with thin wafer technology and is
therefore very cost-effective. The combination of this advanced cell
technology with Day4's DNA Technology further enhance the value
proposition for customers, because efficiency losses from cell to
module can be minimized and substantial savings in silver paste
consumption are realized. Day4's DNA Technology enabled fine line
fingers of 70 micron width and 10 micron height resulting in a 2% short
circuit current (Isc) gain and a 69% silver paste savings when used in
the R&R Heterojunction cells.
The core of Day4 DNA technology is the patented stay-powerful Technology. This innovation is a direct replacement of the
conventional, high temperature solar cell soldering process and is
comprised of a polymer film embedded with a number of copper wires
specially coated with a proprietary, low-temperature melting point
alloy. This establishes a low-resistance electrical contact with the
surface of the PV cell creating over 2,100 independent electrical
contacts. This seemingly simple change to the standard process triggers
a number of far reaching benefits, including improved PV cell
efficiency and mechanical stability, exceptional PV module power
density and better long term performance in the field.
"With better performance from mono and multi crystalline cells, and
serving as a platform for a variety of cell types including large area
back-contact cells, thin-film cells, ultra thin Si cells, large format
Si cells, and heterojunction PV cells; the Day4 stay-powerful
Technology has proven to be key to bringing to market some of the
newest innovations in solar cell design," says George Rubin, president
of Day4 Energy Inc.
"Day4's stay-powerful Technology is an ideal platform for delivering
advanced module technologies in combination with our Heterojunction
technology. The collaboration is an excellent fit for both companies,"
says Dr. Dietmar Roth, CEO of Roth & Rau AG. "We are excited to unveil
a 60 cell module at the 26th European Photovoltaic Solar Energy Exhibition in Hamburg, Germany, 5-8 September, 2011. Visitors are welcome to the
Meyer Burger / Roth & Rau booth located in Hall A1, Stands B7 & A14."
The Day4 DNA brand encompasses three proprietary technologies that
result in superior performance over standard modules: stay-powerful Technology interconnects solar electric cells in a unique way resulting
in superior energy collection even in low light conditions; work-smart Technology ensures solar panels collect electricity when partially
shaded by nearby trees, buildings or debris, generating more
electricity in daily operations and over the life-time of the product;
and live-long Technology enables superior performance in harsh climates due to a
watertight back-sheet with an aluminum layer that protects against
challenging weather conditions, moisture, salt-mist and harmful gasses
from greenhouses and farms that can affect the amount of energy
delivered by a solar PV panel.
