Germany ManzCIGS PV module conversion rate of 16%

Regardless of how fierce the "photovoltaic technology" debate is, everyone has to admit that "advancement of new ideas" is the fate of each industry's development.

According to the recent report of Securities Daily, with the fiery Chinese PV market, some photovoltaic technology routes that once had a "niche" but have broad prospects are getting more and more attention of investors, and the capital's help is very It is possible to speed up the process of industrialization and thus pose a certain threat to the “mass”.

At the recent “Shanghai International Solar Energy Industry and Photovoltaic Project Exhibition”, Manz (manufactured by Germany Manz), a veteran equipment manufacturer in Germany, released the latest research results of CIGS (copper, indium gallium selenide), namely mass production. The conversion efficiency of CIGS thin-film solar modules exceeded 16%, setting a new world record.

What is even more concernable is that related informed sources disclosed to the "Securities Daily" reporter that at present, Manz, Germany, is in intensive talks with several Chinese companies that are interested in cooperation, including not only large-scale central enterprises but also traditional crystalline silicon photovoltaic manufacturing. enterprise.

Conversion efficiency refresh record

Manz introduced that this significant increase in efficiency was mainly due to Manz applying a new generation of CIGS semiconductor materials on glass substrates in the co-evaporation process. And the new CIGS components are designed as an innovative technology that can increase the effective area of ​​power generation and continue to reduce optical losses.

For the prospect of CIGS technology, Dieter Manz, founder and CEO of Manz, Germany, seems to have no doubt. In his opinion, “Compared to the production system of crystal silicon, the Manz CIGS production line has a lower total investment and significantly reduces the time for factory deployment. And the low cost of production is unmatched in the industry.In the future and even now, Manz CIGS technology can provide absolute investment protection for customers and the highest profitability in the entire energy industry.The potential of CIGS technology in the future is enormous, and It will save customers more costs."

In fact, in addition to the above-mentioned “Production efficiency of CIGS Thin Film Solar Modules exceeded 16%”, in the fall of 2014, Manz’s exclusive R&D partner Baden-Württemberg Solar Energy and Hydrogen Energy Research Center (hereinafter referred to as ZSW) also successfully set a world record of 21.7% in the conversion efficiency of the CIGS battery laboratory.

Relying on Manz CIGSfab solution, Manz is currently the only supplier in the world that can provide CIGS turnkey production lines. The annual production capacity can be expanded from 64 MW to 600 MW. According to estimates, Manz believes that the project's return on investment can exceed 15%.

Based on this, Dieter Manz also explained that “In combination with ZSW's technology and Manz's technical experts, we have absolute confidence that in the near future, using Manz's innovative production line in Schwäbisch Hall will create far more than 17% of the A new record of the efficiency of the conversion of components. Manz has mastered the necessary laboratory processes including the post-coating of CIGS. Our new cooperation goal will be to further reduce the cost of electricity in different regions of the world and under various climatic conditions.”

At the same time, the CIGS module with a conversion efficiency of 16% has been certified by TüV Rheinland, the world's leading testing agency.

Production costs below 2.5 yuan/watt

At present, in China, the advantages of Manz CIGS components have been verified at the first CIGS thin film power station in China, Yunnan Shilin Power Station. Judging from their use of the Manz component of the Yunnan Shilin 1 MW CIGS power station, the power output of the CIGS array exceeds that of the crystalline silicon array by about 7% to 10%. More importantly, after two years of wind and sun exposure, the Manz CIGS battery module has not experienced power loss and loss, and still exhibits excellent power generation performance. It has also created power station operators. More power generation revenue.

In fact, Manz’s interest in China is more than that. Lin Junsheng, deputy general manager of Manz Asia Technology, said in an interview with the "Securities Daily" reporter that Manz has a 30 MW production line in Germany. There are power plants in the country that use our manufactured components, so we manufacture and install components from the components. , And then the power generation technology has a complete performance, and has been verified by customers. At present, our CIGS projects mainly focus on equipment and technology, not on production components. There are three reasons for this. First, the production costs in Germany are relatively high and cannot compete with China’s production costs. Second, China has the potential to achieve the economic scale of CIGS. Third, the impact of manpower, electricity prices, etc. in all aspects. Makes Chinese manufacturing cheaper.

Lin Junsheng told reporters that Manz's 150 MW CIGS production line can reduce costs to below RMB 2.5/watt. "And if it expands to 600 megawatts, equipment will become cheaper and material purchases will become much lower, which means that production costs will decline further."

In addition, Manz can provide long-term roadmaps for prospective investment customers of CIGS production systems to support further efficiency improvements. "For example, the efficiency is now over 14%, and it will be upgraded to 17% in the future. Basically, it can be completed on our existing production line and there is no need to replace new equipment." Lin Junsheng also introduced, "In addition to the initial equipment In the future, more equipment will be manufactured in the country. This will not only shorten the delivery date of the equipment, but also increase the ratio of domestic manufacturing equipment."
