With a module efficiency of 16 percent, Manz AG (Reutlingen, Germany) presents a new efficiency world record for CIGS thin-film solar photovoltaic (PV) modules on April 27th, 2015 at SNEC in Shanghai, the world's leading trade fair for the photovoltaics industry.
In doing so, Manz is pushing forward into a new dimension and closing the efficiency gap that has previously existed in between CIGS and the multi-crystalline PV technology that is still prevalent today, the company emphasizes.
In the fall of 2014, the Center for Solar Energy and Hydrogen Research of Baden-Wuerttemberg (ZSW), Manz's exclusive development partner, was able to demonstrate the superiority of CIGS technology in comparison to crystalline solar cells in the laboratory, with a world-record efficiency of 21.7% in cell format.
Significant PV module performance reached on equipment for mass production.
With Manz's new world record for module size, this superiority has now been proven in production. The significance of this result is all the greater since the high-tech equipment manufacturer produced the world record module on its innovative production line for CIGS technology at its location in Schwaebisch Hall, on equipment for mass production.
The significant increase in performance was achieved mainly by the next generation of CIGS semiconductor material, which Manz applies to a glass substrate in the so-called co-evaporation process. Additional technological innovation is a new module design for increasing the active module surface. In addition, Manz engineers were able to sustainably reduce optical losses.
Dieter Manz: Today, CIGS modules from Manz already offer the lowest electricity generation costs in comparison to the still prevailing crystalline silicon technology
“Our performance parameters are world-class. With significantly lower production costs compared to crystalline solar cells, CIGS technology will play a large role in the coming investment cycle of the photovoltaics industry,” Dieter Manz, founder and CEO of Manz AG, is convinced. Today, CIGS modules from Manz already offer the lowest electricity generation costs in comparison to the still prevailing crystalline silicon technology, he emphasizes.
Manz pledges a secure investment option with maximum profitability
With Manz CIGSfab, the Reutlingen equipment manufacturer is currently the only supplier of turnkey CIGS production lines in the world, with a scalable production capacity of 50 to 350 Megawatts per year.
With an internal rate of return of more than 15 percent, an investment in a fully integrated CIGS line from Manz is one of the most profitable in the entire energy sector, the company notes.
“As a high-tech equipment manufacturer with unique process know-how, we offer an unbeatable combination of arguments in favor of investment in a CIGS production line,” explains Dieter Manz.
“A lower total investment in comparison to crystalline systems, significantly shorter implementation time for the plant, as well as the unrivaled low production costs. An investor in Manz CIGS technology is guaranteed absolute investment security, with the highest margins in the entire energy sector – in the future, and even today. The future potential of CIGS technology is enormous and will lead to further cost reductions.”
21.7 percent cell efficiency achieved in the laboratory
Manz's 16 percent efficiency world record is the result of a long-term development partnership with the Stuttgart Center for Solar Energy and Hydrogen Research of Baden-Wuerttemberg (ZSW). Following the presentation of 21.7 percent cell efficiency in the laboratory by the globally leading research institute for CIGS thin-film technology in the fall of 2014, Manz was able to transfer the essential insights of the technology that was used to mass production.
“This great success demonstrates the future potential of CIGS thin-film technology and emphasizes nothing less than our claim to technology leadership,” says Dieter Manz.
“Building on the know-how of ZSW and our own experts, it is thus absolutely realistic that we will already be able to present module efficiencies of significantly higher than 17 percent in the near future, produced on our innovative production line in Schwaebisch Hall. We have already mastered the necessary processes in the lab, such as the after-treatment of CIGS coatings. The goal of our joint efforts is the further reduction of electricity costs – around the world, under all climatic conditions.”
TUV Rheinland certifies 16 percent record efficiency
Manz's world record with 16 percent efficiency was certified last week by the testing organization TUV Rheinland. Manz AG offers potential investors in CIGS production systems a long-term road map for further efficiency increases, whose milestones have always been achieved ahead of schedule in recent years.
