Summarized, co-extruded backsheets based on PP show great potential to be a valid replacement of standard PET based backsheets in PV modules. On the one hand, the PP backsheet so far proved excellent stability, exhibiting no severe material degradation after extended exposure to temperature, humidity and irradiation.
Therefore, in contrast to test modules using Ethylene Vinyl Acetate (EVA) encapsulants and PET backsheets, no silver grid corrosion was observed for modules using PP backsheets. Co-extruded backsheets based on PP show great potential to be a valid replacement of standard PET based backsheets in PV modules.
To address the manifold requirements, usually polymeric multi-layer films are used. The first generation of backsheets were developed in the 1980s, consisting of polyvinyl fluoride (PVF) on the outside (inner and outer layer) laminated via a thin adhesive layer to a polyethylene terephthalate (PET) core layer.
Also, the backsheet did not exhibit embrittlement after neither aging test and retained its high ductility. Rummens et al. exposed test laminates (glass/EVA/cell fragments/EVA/PP backsheet) up to 24,000 h to UV irradiation (IEC 62788-7-2 A3 conditions), without observing any embrittlement or discoloration of the polypropylene backsheet.
Epoxy sheets are being developed with embedded sensors and conductive pathways, paving the way for intelligent solar modules. These smart backplanes can monitor performance
