centrotherm presents groundbreaking products and processes for the
manufacturing of high-efficiency solar cells at the SNEC PV in Shanghai
- centrotherm c.REG regeneration furnace for the reduction of light
induced degradation (LID)
- PECVD process for aluminum oxide coating (AlOx)
- Low-pressure boron diffusion for bifacial n-type solar cells
Blaubeuren, April 27, 2015 - From April 28 to 30 centrotherm will be
presenting new pioneering products and processes for the production of
crystalline solar cells at the main Asian photovoltaic trade fair SNEC PV
in Shanghai. These allow manufacturers the next step from the standard
solar cell to the production of highly efficient PERC and n-type solar
cells. The newly developed centrotherm products and processes can be
optimally integrated into existing mass production and achieve cell
efficiencies of more than 20%.
Newly developed regeneration furnace c.REG reduces significantly light
induced degradation (LID)
After first exposure to light mono-crystalline p-type solar cells might
suffer performance losses due to light induced degradation (LID). This
effect is ascribed to recombination active boron oxygen (B-O) complexes in
the wafer bulk that reduce conversion efficiency substantially.
To passivate B-O-defects centrotherm developed a regeneration process and
corresponding equipment that is applied directly after fast firing, after
sorting or even before module manufacturing. LID is significantly reduced
with the belt furnace c.REG. A particularly efficient and quick
regeneration can be achieved in connection with the direct plasma process
of the centrotherm PECVD system c.PLASMA.
centrotherm aluminum oxide PECVD process for the manufacture of PERC solar
cells
Many cell manufacturers are turning towards more complex cell architectures
with higher efficiencies. Therefore, the next generation of crystalline
solar cells requires a highly effective surface passivation of front and
rear side of the wafer.
The newly developed centrotherm process for the rear side passivation by
AlOx/SiNx stacked layers is characterized by excellent surface passivation
properties. Furthermore, the centrotherm c.PLASMA PECVD system provides
improved process flexibility for further dielectric layers (SiONx, SiOx,
etc.) in both mono and multi solar processing.
The process is offered as an upgrade package for the centrotherm PECVD
system c.PLASMA as well as in new systems.
Low-pressure boron diffusion for bifacial n-type solar cells
N-type solar cells are increasingly getting into the focus of solar cell
manufacturers as they have a higher efficiency potential and show no light
induced degradation.
In the framework of the BiSoN alliance with the ISC Constance, centrotherm
is offering process and system packages for the mass production of this
cell concept since last year. Now, centrotherm launches an additional new
low-pressure process for highly efficient boron doping with its R&D partner
in Constance.
The formation of a well passivated boron emitter is achieved with this
process, which is crucial for many n-type cell structures. In addition,
solar cell manufacturers achieve significant cost reductions while
maintaining high quality production. On the one hand by the reduction of
boron consumption by up to 75% and on the other hand by eliminating the
boron silicate glass (BSG) removal.
The process is offered as an upgrade package for the centrotherm diffusion
furnace c.DIFF as well as in new systems.
"With our product and process innovations we offer our customers solutions
to their manifold and very different requirements on their path to highly
efficient solar cell concepts," notes Dr. Josef Haase, Senior Vice
President Technology Photovoltaics, before adding: "It is essential for the
customer, that centrotherm systems deployed in their production can be
upgraded to the latest state-of-the-art with process and hardware packages.
That offers the customer flexibility for the future along with the
performance of our systems and processes.
