Film-free TPedge module

Thanks to the completely new TPedge technology and a simplified module structure, wafer-based solar modules can now be produced much faster and at significantly reduced costs compared to standard wafer-modules.

Cost reductions with TPedge

The TPedge technology reduces the costs of the module production without solar cells by 30 to 40 percent – at an desired cycle time of 45 seconds per module line. As a result, the overall costs of a PV module can – depending upon the cost level of the solar cells – be reduced by approximately 14 percent.

The time and cost savings are as a consequence of a simplified modular structure and a completely innovative production technology. The cell array is locally fixed between two glass lites. The use of films and the associated lamination is not necessary. The edge sealing of the TPedge module is carried out via the application of the thermoplastic material at 130 C, even an additional aluminium frame is not necessary.

Innovative leap in module production

Bystronic glass developed the technology for the production of the TPedge module in cooperation with the Fraunhofer Institute for Solar Energy Systems (ISE). The production lines for TPedge modules can be designed in various expansion stages. In the serial production line, it is possible to manufacture a module in under a minute – compared to the 16 minutes that are required for the usual standard procedure. The new production principle is inspired by the sealing technology used in insulating glass production. This development of the TPedge process for the production of modules with thermoplastic sealing on the glass edge marks a great innovative leap in the entire module production.
