Roth & Rau achieves industry-leading silver savings in solar cells

editor, 21 September 2012



- 50 – 70% savings in silver

- Process developed for front and rear side coating with nickel

- Production tool available for immediate use in solar cell production

Meyer Burger Technology Ltd (SIX Swiss Exchange: MBTN) today announced that its Group member Roth & Rau AG [Frankfurt stock exchange: R8R] has developed a process which uses inexpensive nickel in busbar metallisation for the electrical contacting of solar cells. The coating process includes both the front and rear sides of the cell within a production tool. This process, which is immediately available, significantly differentiates Roth & Rau from its competitors.

Depending on the contact technology, a saving of between 50 and 70% in expensive silver and therefore a significant reduction in the production cost of solar cells can be achieved. A further benefit from the process is the fact that nickel is a readily available material. This means that solar cell manufacturers are not tied to specific suppliers as is the case with other materials.

The HELiA system, which was developed primarily for the production of high efficiency heterojunction cells, coats the solar cells with nickel in a shortened system configuration to form the front and rear busbars. This is achieved by means of a sputtering process. In contrast to other systems, the HELiA system permits simultaneous processing not only of the rear surface but also of the front surface on which there is a significantly greater potential for savings.

A further decisive benefit of this new process is the outstanding adhesion of the cell connectors to the front and rear surfaces of the solar cell as a result of the nickel metallisation in standard soldering processes. The metallisation of the fingers can thus take place regardless of the electrical characteristics of the busbar and be optimised to match them. In this way, the metallisation of the fingers is de-coupled from the solderability of the busbar, thereby enabling the use of new pastes and metallisation processes that do not currently achieve reliable solderability. The performance of solar cells coated with this process is comparable with that of solar cells metallised in the conventional way by screen printing.

The concept and associated system will be presented at the Meyer Burger stand (Hall 3, E2) at the upcoming EUPVSEC trade fair in Frankfurt from 25-28 September.

Next step taken in integration process within Meyer Burger Group

editor, 03 October 2011

- Restructuring of management board team

- Dr. Dietmar Roth becomes member of Board of Directors at Meyer Burger Technology AG

Hohenstein-Ernstthal, 3 October 2011 – As part of the integration of the Roth & Rau Group within the Meyer Burger Group, the Supervisory Board of Roth & Rau AG has taken a further major step by restructuring the management board team. Dr. Dietmar Roth will step down as Chairman of the Management Board with immediate effect and move to the Board of Directors at Meyer Burger Technology AG. “I have always stressed that I would stand back from my operational responsibilities at the right time. That time has come now that the takeover by Meyer Burger has been successfully completed and we have found high-quality, experienced managers keen to shape Roth & Rau`s further successful development in the long term. Given the length and depth of my involvement with Roth & Rau AG, however, it is only natural that I should offer active support to the newly restructured Management Board and advise them in all key issues”, commented Dr. Roth.

The Supervisory Board has appointed Peter Frankfurter as the company`s new Chief Financial Officer (CFO) with immediate effect. The 48 year-old business graduate has longstanding management experience as CFO and in other commercial management roles at international industrial companies. Frankfurter was previously Commercial Director at SUMIDA Europe GmbH, one of the world`s key manufacturers of inductive components and modules for the electrical and electronics industries.

Peter R. Manolopoulos (42) will assume responsibility for operations as COO also with immediate effect. Born in Wuppertal, Manolopoulos can look back on a long track record of international activity as managing director and division head at mechanical engineering and plant construction companies, focusing on energy technology. Having studied business administration, he first gained experience in areas including strategy and M&A at Babcock Borsig AG. In 2002, he moved to the publicly listed GEA Group AG, where he held various management positions, most recently prior to joining Roth & Rau AG with responsibility for the wet cooling division as Managing Director of GEA Energietechnik GmbH.

Thomas Hengst will continue to be responsible for the sales division in the Management Board in his role as CSO of Roth & Rau AG. Furthermore, Peter M. Wagner, to date Supervisory Board Chairman of Roth & Rau AG will initially assume the role of Management Board Chairman. “We will not be filling the traditional CEO post following the successful integration of the company into the Meyer Burger Group. Rather than that, Peter Frankfurter, Peter Manolopoulos and Thomas Hengst will manage the operations of the Roth & Rau Group as a team of three. For the transitional period the planned delisting of Roth & Rau AG has been implemented, I will therefore assume the role of CEO. In this, my main focus will be on pressing rapidly and efficiently ahead with the integration process to exploit the synergy effects available to the combined group on the market”, explained Wagner with regard to his role in the new management board team.

The company`s Management Board thus currently comprises four members. Due to Peter M. Wagner`s appointment to the Management Board, the Supervisory Board has requested its former member Prof. Alexander Michaelis to assume the position thereby temporarily vacant. Wagner`s deputy, Andrea Sieber, will assume the Chairmanship of the Supervisory Board.

Roth & Rau announces preliminary consolidated results for the 2010 financial year

editor, 23 February 2011

- Sales growth of 35.9 % to € 268.9 million

- EBIT of € -25.9 million after special items

- Strategic focus on single equipment business resolved

Hohenstein-Ernstthal, 23 February 2011 – Based on preliminary figures, the Roth & Rau Group generated sales of € 268.9 million in the past 2010 financial year. This corresponds to growth of 35.9 % on the previous year’s figure of € 197.9 million. The Group’s order situation also developed dynamically, with new orders rising by 103.9 % to € 399.1 million (previous year: € 195.7 million). Orders on hand therefore totalled € 335.0 million as of 31 December 2010 (previous year: € 204.8 million). This development has been driven above all by the highly successful market launch of the new SiNA generation. The strong level of demand for production equipment has also continued in the first quarter. New orders totalling € 49.7 million had been received by 18 February, of which around 75 % were for single equipment and around 15 % for service and spare parts.

The Group’s earnings performance in the past year > affected by special items of around € -51.2 million (of which € 42.9 million under EBIT and € 8.3 million under net financial expenses). As a result, preliminary earnings before interest and taxes (EBIT) amounted to € -25.9 million in the 2010 financial year (previous year: € 16.1 million). EBIT before special items amounted to € 17.0 million.

The special items related to impairment losses of around € 8.5 million already recognised for turnkey projects as of 30 September 2010 and of around € 12.5 million (of which € 4.2 million under EBIT and € 8.3 million under net financial expenses) due to the risk of insolvency at the US customer SpectraWatt. Both developments were already announced as soon as they arose. Moreover, the Group has also recognised further impairment losses of € 11.0 million in connection with existing turnkey projects and provisions of € 9.6 million for legal and tax risks relating to major projects still underway. Furthermore, as part of a new strategic alignment that, among other aspects, involves streamlining the Group’s product portfolio, the Management Board has discontinued activities in specific product groups and thus also in related development projects. This made it necessary to recognise further, one-off impairment losses of around € 3.1 million.

One major one-off item of € 6.5 million also resulted from the necessary conversion of the accounting treatment of SiNA series single equipment from the percentage of completion method to measurement at cost, which will involve the respective profit being deferred to the 2011 financial year.
