based on upgrade package • Successful transfer of laboratory

production lines with selective emitter laser doping

Blaubeuren (euro adhoc) - January 20, 2011 - centrotherm
photovoltaics AG has successfully transferred excellent laboratory
results to production operation at the Chinese customer Dongfang Magi
Solar: an average 18.5 percent efficiency was achieved on batches
totaling some thousands of solar cells made from mono-crystalline
material on a standard 156 x 156 mm (240 cm²) surface. These high
figures for solar cells made of mono-crystalline material were
achieved using an upgrade package for selective emitter technology
and exceeded the current industrial average.

"Within a few weeks, we have realized in close co-work with our
customer Dongfang Magi Solar the process adjustment and transfer from
our R&D laboratory situation to mass production, and we will achieve
this even more rapidly with further installations", comments Dr.
Peter Fath, CTO of centrotherm photovoltaics. "The upgrade packages
enable our customers to further boost cell efficiency, as well as to
manufacture on an even more efficient basis. Along with the
technology's ease of integration into the production process, the
upgrade package solution is distinguished by low capital investment
expenditures (capex)."

"We are very satisfied with the rapid implementation, and the good
and stable efficiency results. With this new selective emitter
technology and an average efficiency of 18.5 percent in mass
production Dongfang Magi Solar will be one of the performance leaders
in this industry", notes Wen Zhang, CEO of Dongfang Electric Magi
Solar Power Technology Co. Ltd. The parent company Dongfang Electric
Corporation is one of the largest state-owned conglomerates in China.
"We are currently in negotiation with centrotherm for further upgrade
packages with the selective emitter technology for all our remaining
production lines", CEO Zhang goes on to comment.

Laser diffusion allows for a selective emitter structure with low
phosphorus doping on the entire upper surface of the cell, except for
the points along the metallization. These improved emitter properties
enable very good contacts, and high solar cell performance.
