After completion of the cells, they are electrically series connected and assembled into a solar module. Moreover a junction box is attached that will ensure suitable power output. Within current solar modules technology, one big eco-challenge is the fact all module components are physically linked to each other by lamination and soldering. The only potential for recycling are destructive processes that result in lower grade materials in form of granules. Current PV modules also contain a vast amount of organic materials (EVA for encapsulation, PVF in backsheets)
As Apollon Solar’s NICE-modules are already designed for disassembly, in Eco-Solar Apollon will focus on further reduction of the module BOM (Bill of materials) focussing on a frameless version of the PV module, and integration of electronics in the junction box, to monitor the performance in the field. Moreover, Apollon will demonstrate that module assembly of the Eco-Solar cells will result in comparable module output as with current non-eco-friendly state of the art module technology.
Finally, Apollon Solar will demonstrate the disassembly of modules into their major components (glass sheets, copper wires, cells) allowing for their recovery as entire pieces with a high added value and strong potential for re-use (in PV or other industries).
The benefits of material savings will be demonstrated via the LCA carried out by bifa.
