The Meyer Burger brand stands for expertise, advanced technologies and precision products which are based on semiconductor technologies, with a focus on photovoltaics.
Throughout the entire photovoltaic value chain we enable our customers to reach the lowest manufacturing and production costs in the industry by delivering customized equipment solutions and integrated systems.
Meyer Burger's Specialized Technologies portfolio has evolved from technologies which were successfully implemented in the PV market and which now cover a broad range of applications in other high-tech markets.
It is not only our high quality technology and equipment which our customers benefit from but also our extensive service skills such as project planning, engineering concepts and customized service packages are convincing factors in the market.
Highlight: Diamond Wire Diamond wire technology achieves further reductions in cost per wafer. The environmentally friendly water-based sawing process cuts the brick at double the cutting speed compared to standard slurry cutting processes. This increases production output significantly and maximises machine capacity.
Quartz sand Quartz sand is the raw material for photovoltaic systems. In a series of complex production processes, it is transformed from its original form into solar panels capable of producing electricity.
Cropping Cropping is the process in which the ingot is cut into segments of optimal length, and top end and tail, test wafers
Grinding Subsurface damages and geometric irregularities are eliminated and the brick prepared with the final wafer geometry during grinding which enables optimal process stability in downstream processes. It is the base for higher yields during wafering.
Gluing The homogeneous application of the glue ensures highest yield in follow-on processes. By marking each brick with the HSC Code, it is possible to trace the position of the brick and the wafers cut from it within the production process.
Wafering Using diamond wire cutting technology, the hard and brittle silicon brick is cut into ultra-thin high-quality wafers which are ideal for application in the trendsetting heterojunction (HJT) cell process.
Highlight: Heterojunction Technology (HJT) HJT combines the advantages of crystalline silicon solar cells and thin film technologies enabling solar cells to reach higher degrees of efficiency at a lower cost of production.
Texturing For high efficiency HJT cells, damages from cutting have to be completely removed and a special texture created by wet chemical processes. The wafers are also put through a special cleaning process.
PECVD coating The surface of the cell is passivated (p/n junction) in order to prevent energy loss within the cell. The intrinsic and amorphous silicon layers are separated without cross-contamination, thus achieving passivation with a high longevity.
Highlight: Contacting busbarless cells Meyer Burger’s contacting system for contacting busbarless cells for IV/EL performance measurements ensures that the shadowing on the cell is minimised and that the IV measurement is both precise and highly reproducible. Using perpendicular wires on the front and back sides instead of standard contact pins ensures a uniformly distributed pressure on the cell and thus a capability of contacting very thin cells < 120 μm.
Sorting After sorting of the solar modules into their respective performance categories, they are stacked on euro-pallets and released for transport.
Highlight: DragonBack® Solar modules are sold based on performance categories making the precise performance measurement modules critically important. Meyer Burger sets the standard for industrial measurement technology with its innovative solutions for accurate power rating of high efficiency modules. Meyer Burger’s award winning performance measurement technology for high efficiency modules is A+A+A+ certified by TÜV Rheinland.
Solar systems Meyer Burger is actively engaged in implementing future-oriented energy strategies and realising intelligent energy systems. Together with partners in industry, research and politics, at the trade association level and with our customers, we aim to prove that photovoltaics can contribute considerably to the future energy supply. We are proactively involved in such topics and issues as energy generation, energy storage technology and energy efficiencies.
