The versatile U-IBC 2.0 photo voltaic PV module sequence of Euronergy has a weight of two.5 kg/m2 utilizing another technique to the standard technique of photo voltaic cell interconnection of modules.
Euronergy, a European PV firm targeted on superior back-contact photo voltaic cell and module expertise, has made advances in planar electrical connection (PEC) expertise, changing the standard ribbon strategy for interconnection of photo voltaic PV cells in a module. PEC expertise as a substitute makes use of patterned planar-conductive-foils mixed with a punched insulating encapsulate composite (IEC). The firm’s R&D workforce has efficiently adopted PEC expertise in its versatile U-IBC 2.0 module sequence, which makes use of interdigitated again contact (IBC) photo voltaic cells.
Thanks to Euronergy’s distinctive PEC expertise, the insulating encapsulation composite (IEC) packaging materials has been independently developed, weighing solely 2.5 kg/m.2all-black look, higher low-light response efficiency, and suitability for European utility situations, the corporate’s U-IBC 2.0 versatile module was chosen for the Innovation Boulevard throughout Solar Solutions Bremen 2024. In addition, it was chosen as a finalist for The smarter E AWARD 2024 within the Photovoltaics class.
The chief scientist of Euronergy, Prof. Martin Green, believes that PEC will change into the dominant expertise for producing extremely dependable PV modules ─ particularly light-weight modules, versatile modules, and PV roof tiles.
As solar energy will increase in recognition, there may be rising concern in regards to the reliability of the modules. While energy capability and conversion effectivity are largely decided by the kind of photo voltaic cell expertise, reliability is determined by the kind of expertise used for the modules. The method every producer approaches the interconnection between cells tremendously impacts the efficiency and reliability of the modules.
Traditionally, the interconnection between cells is completed by utilizing ribbons (copper strips coated with soldering tin) that join the entrance electrodes of 1 cell to the again of its neighboring cell or to connecting the electrodes on the again of 1 cell to these on the again of its neighboring cell.
However, utilizing ribbons for interconnection has its drawbacks. The stress on the module edges as a consequence of bent ribbons and on the cell edges as a consequence of soldering could cause micro-cracks, which have been recognized as main causes of energy degradation and reliability points in PV modules. At the identical time, using the heavy metallic lead (Pb) in soldering supplies has change into a significant concern with regards to recycling modules.
PEC expertise is engaging as a way that addresses the issues of stress and Pb use with conventional ribbon interconnections.
Euronergy will showcase extra new merchandise on the firm’s sales space (A1.236) at Intersolar Europe 2024.
