Kahl am Main, 05 June 2023 – With the GENERIS PET vacuum coating system, SINGULUS TECHNOLOGIES offers a new process machine for the passivation of the cut edges of solar cells. It was developed to improve the efficiency in the processing of half-cell, multi-cell, and shingle cells. Edge passivation aims to improve efficiency by minimizing unwanted effects at the cut edges. Compared to unpassivated cut cells, the GENERIS PET coating system enables an efficiency increase of up to 1%. As an inline solution, which depending on the configuration can achieve, for example, a half-cell throughput of several GW per year, the system is suitable for various cell and cut formats and can be integrated into existing cell and module lines.
Dr.-Ing. Stefan Rinck, CEO SINGULUS TECHNOLOGIES: “Our GENERIS PET offers an industrially viable solution for edge passivation. It features high throughputs at low costs.” Dr. Rinck adds, “The machine can process half cells, multiple cells and also cell strips (shingle cells) after cutting. Our unique tray design allows processing of thousands of cell parts per tray with high packing density. In the process, the passivation layers are precisely applied to the cut edges without undesirable effects on the cell surfaces.”
Half-cell and shingle technologies are becoming increasingly popular because they result in higher efficiency modules. By cutting the cells into smaller units, the electrical resistance of the metallization decreases, resulting in improved conductivity and higher efficiencies.
The application of Passivated Edge Technology (PET) can significantly increase efficiency even in half-cell modules. The effect is more pronounced with shingle cells. With shingle matrix technology, it is possible to break new ground for future-oriented modules. The constellation of cells in a matrix leads to a new benchmark for maximum efficiency and to unprecedented possibilities in module design due to the improved shading tolerance.
SINGULUS TECHNOLOGIES cooperates with the Freiburg-based company M10 Solar Equipment GmbH (M10SE) in the optimization of the shingle cell modules.
