Back-contact module technology from Solland Solar and SCHOTT Solar receives VDE certificate

Back-contact module technology from Solland Solar and SCHOTT Solar receives VDE certificate (PresseBox) (Heerlen/Aachen, ) The German Association for Electrical, Electronic and Information Technologies (VDE) has certified the back-contact module developed jointly by Solland Solar and SCHOTT Solar in accordance with the IEC standard 61215 ed.2 & 61730. This is thus the first fully certified, mass manufactured module whose solar cells are manufactured on the basis of Metal Wrap Through (MWT) technology, are interconnected by a special back-contact foil located on the backside.

This development once again demonstrates the quality leadership and innovative performance that European module manufacturers have achieved. The back-contact module is a premium product that distinguishes itself from conventional module technologies thanks to the extremely clever way in which the backsides of the modules are connected to enable much better power flow. The backside contacts even minimize shadowing and resistive losses. In the highest performance class, for instance, the 60 multicrystalline cells contained in each module generate an energy yield of up to 260 W peak and offer efficiency of 16.4 percent.

This premium product also sets a new standard for attractive appearance. The unique visual appearance of the cells in combination with the black backside foil and frame produce a rather sophisticated and homogeneous overall design. The module is particularly well-suited for the roofs of private homes, due to the fact that it generates a high output per m².

The next step calls for Solland Solar to begin marketing the initial volumes produced during pilot manufacturing under the name Solland Sunweb®. Furthermore, both companies plan to continue to work together on further developing their back-contact technology due to the immense potential it holds to increase efficiency and reduce costs. One of their goals is to apply the most recent successes SCHOTT Solar has had in developing monocrystalline cells that even resulted in a high efficiency of 20.2 percent to this MWT technology.

About Schott Solar:

SCHOTT Solar, with its high-quality products, enables the potential of the sun as a nearly inexhaustible source of energy to be utilized. And it's for exactly that reason that SCHOTT Solar produces important components for photovoltaic applications and solar energy plants. In the photovoltaic industry, the company is one of the few integrated manufacturers of crystalline silicon wafers, cells and modules. In thin-film technology, SCHOTT Solar also describes itself as an advanced supplier due to having over twenty years of experience. And in the production of receivers for solar power plants, SCHOTT Solar sees itself as a market and technology leader. The receivers are key components in large-scale power plants that generate electricity from solar energy centrally on the basis of parabolic trough technology and are able to supply entire cities with power.

SCHOTT Solar has production facilities in Germany, the Czech Republic, the USA and Spain. The innovative power and technological competence of the company date back to the late 1950s. SCHOTT Solar is a wholly owned subsidiary of the international SCHOTT technology group. SCHOTT develops special materials, components and systems for the household appliance, pharmaceutical, solar energy, electronics, optical and automotive industries. With around 17,500 employees, the SCHOTT Group generated a worldwide turnover of about 2.9 billion euros in fiscal year 2009/2010.
