MULTIFUNCTIONAL COATINGS LIGHT HARVESTING Laminated By-Pass Diodes COST EFFECTIVE BARRIER LAYER FOR FLEXIBLE THIN FILM SOLAR MODULES PV module innovation transfer and costs: intermediate assessment PET sheet barrier coating front eletrode absorber back electrode PI substrate encapsulant back sheet encapsulant Modules laminated with a PET foil with nanometric Al2O3 or SiNx barrier had a similar output at 1000 hour of 85oC/85 % RH damp heat exposure as with a reference (high grade) front sheet. CIGS module on poly-imide substrate, laminated on back sheet, bonded to PET foil with Al2O3 coating. Problem description: The encapsulation costs are the main drawback for current flexible light weight applications of thin film modules. This innovation will open new market segments for building integrated PV where typical PV system cannot be applied because of their high additional weight.
