Communication with world-famous scientist


Cooperated with University of Illinois Urbana-Champaign，Liu Yiming newlydeveloped wxAMPS based on AMPS. The wxAMPS is convenient as well ascompatible for several kinds of solar cells, especially effective for CIGS solar cellswith complicated multi-layer properties. wxAMPS is a stable and strong one-dimensional solar cell simulation software, and has received attention from topresearch group such as NREL and IBM.

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


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


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


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.


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.
