Trina Solar and ANU Jointly Develop High Efficiency Solar Cell
Highest Efficiency for a Back Contact Silicon Solar Cell
China, Feb. 28, 2014 /PRNewswire/ -- Trina Solar Limited ("TSL"
or "Trina Solar"), a global leader in photovoltaic modules, solutions
and services, announced today that researchers from Trina Solar and the
Australian National University ("ANU") have jointly developed a new
high-efficiency solar cell.
laboratory scale Interdigitated Back Contact ("IBC") cell was
developed at the Australian National University Centre for Sustainable Energy
Systems under a research and development contract with Trina Solar through a
collaboration contract with the Solar Energy Research Institute of Singapore
(SERIS). After two years of research, funded by Trina Solar, the ANU has
developed, with contribution from Australian consulting firm PV Lighthouse, an
IBC silicon solar cell, which was independently tested by the Fraunhofer CalLab
in Germany to be able to deliver an efficiency of 24.4%, putting it among the
most efficient solar cells to date.
Solar is now developing a commercial version of the IBC solar cell as well as
an IBC PV module. The commercial cell has already reached an efficiency greater
than 22% for a 125mm by 125mm IBC solar cell, and 238W for an IBC PV module
(based on 72 cells), which was independently tested by the National Center of
Supervision and Inspection on Solar Photovoltaic Products Quality of China.
Though it is currently in laboratory scale, the new solar cell will soon be
ready for industrialized mass production.
are delighted to collaborate with leading scientists at ANU on this exciting
new development in our cell technologies," said Dr. Pierre Verlinden,
Vice-President and Chief Scientist of Trina Solar. "This marks a milestone
in solar cell research with an improved IBC cell efficiency of 24.4%. This
world-class efficiency demonstrates our commitment to leading innovation in PV
technology. We remain committed to engaging in effective partnerships with the
best PV research centers, which are fundamental to delivering R&D
is the highest efficiency independently confirmed for a conventional IBC solar
cell to date," said Professor Andrew Blakers, Director of the Centre for
Sustainable Energy Systems at the ANU Research School of Engineering. "The
results mean the laboratory cell technology can now be further developed for commercial
solar cells. The work is expected to lead to commercial solar cells with
improved efficiency, allowing more power to be generated from a given area of
rooftop solar module."
Blakers added, "The ANU has been working to develop highly efficient back contact
silicon solar cells, which have both positive and negative metallic contacts on
the rear surface. That allows the surface facing the sun to be uniformly black,
without the metal electrodes present on most solar cells. The back contact cell
structure enables the end user to gain more electricity per unit area and a
more favourable appearance."
