CIGS PV plant has larger electric capacity than Si solar cells in Shilin, China
Beijing Sanglin company has purchased Manz CIGS modules and build a PV plant
compared with Si solar cells. The results indicate that the electric capacity produced by
CIGS solar cells is 10% higher than that of Si solar cells.

1)These CIGS production lines unprofitable(economic crisis or tech-mature)
2)Manz indicates that the cost may reduce to 0.3$/wp if the capacity reaches
200MW( the promise can be proved?)
3)Localization may reduce the cost(how to do?)
4)Investment risk(financial community and technology)
The success of localization on production line in advance is necessary, which
will dispel doubts and gain recognition from financial community.
The problems for purchasing and introducing oversea production line
Inst. Of Photo-electronics
China has already become a PV Industrial country relying on importing Si
production line and technology. It may also be effective to import CIGS
production lines.
The localization of CIGS equipment, raw materials and staff on the line may
be an effective measures to reduce the cost.
The research group and Manufacturer together developed the CIGS solar cell
equipment is one of the most important part in localization.
Localization of CIGS production line
Inst. Of Photo-electronics
Turn a-Si production line into CIGS oneCIGS fabrication equipment is the kernel of production line
If we changed the PECVD system to CIGS fabrication system,coupledwith other equipment, The cost of CIGS module will be far less than that in Siproduction line.

Linear evaporation source for CIGS fabrication system
“Large-area continuous deposition system for CIGS module” is the kernel of CIGS equipment.
1)high-temperature stable and long-time running;
2)the design and lifetime of linear evaporation ;
3)Dust suppression in evaporation chamber;
4)in-line monitor for element ratio.
Problems of equipment R&D
Inst. Of Photo-electronics
CIGS industrialization may have breakthrough in coming 10 years
• National strategy for PV core equipment
1)Ministry of Industry and Information Technology《中国制造2025》;
2)National development amd reform commission, National energy administration《能
源技术革命创新行动计划(2016-2030年)》及《能源技术革命重点创新行动路线图》;
* Hanergy, CNBM and Shanghai Electric has introduced oversea production lines;
* Successfully remodel Si-based production line.
Inst. Of Photo-electronics
The capacity of CIGS solar cells is similar with Crystalline silicon cell
and once its technology becomes mature and GW scale, it will have lower
plant cost compared with Crystalline silicon cell.
The PV development contributes a lot to the world wide clear energy
consumption. Although the China PV industry is weak in High-end
equipment and innovation, we really eager to new products and
technology.
We hope that Hanergy, CNBM and Manz’s cooperators may be
successful , and pave the way for the development of CIGS industry in
China.
