2 Understanding the barrier A broad survey

3 How likely would Swiss owners install PV? A broad survey

4 What are their main motivations? A broad survey

5 PV as a new construction material multi-functionality PV modules Ac)ve Construc)on Materials Ø Produce electricity Ø OpGmized for powerful PV plant Ø Holds essengal architectural funcgons, both technical and aesthegc Ø Comply with construcgon and safety norms

6 PV as building element A new paradigm AcGve façades should become a construcgon standard: Ø The acgve element acts as a building material Ø It give to the building an architectural and esthegc value Ø It does produce energy and therefore generate revenues and become cheaper than a convengonal façade

7 Cost comparison some numbers Ø Average cost of AcGve Glass: 280 /m2 Ø Cable, Inverters, MounGng: 120 /m2 Total average cost of an acgve façade: 400 /m 2 Annual producgon per m 2 for a façade: 130 kwh, electricity value: 0,23 /kwh, revenues per m 2 : 30 /year Ø return of investment is less than 10 years.

8 CSEM key infrastructures From coatings, to cells, to modules, t o systems Technology infrastructure Pla>orms Thin film CoaGng & lasering Cells Pilot lines Modules R&D lines Polymers compounding Metrology and characterizagon TesGng and reliability with SUPSI storage R&D center (with BFH) Over 2000 m 2 of lab and faciliges in Neuchatel 8

9 Module technology at CSEM Strategic topics Photovoltaïque intégré au bâ)ment (BIPV) Architecture et esthégque Approche transformagve à bas coût Produits spéciaux mobilité, portable, electronique Fait «sur mesure» Matériaux et fiabilité FormulaGon dédiée & extrusion d encapsulant Tests et prédicgon de modes de dégradagon

10 Polymer platform For dedicated encapsulant ü 30m 2 lab, packaging foil of 0.1 to 2.5 mm thick and width of 20 cm ü Compounder / pellegzer (capacity: 4 Kg/h) ü Flat cast film extrusion / chill roll (capacity: 10kg/h) ü Rheological analysis, characterizagon ü Customized encapsulant and polymeric material ü LifeGme assessment ü Deep knowledge and understanding of failure mechanisms ü Accelerated aging and tesgng (DH, TC, UV)

11 Polymer platform Custom made EVA

12 Polymer platform Custom made PO Ø PO-based encapsulant formulagon with customized viscosity profile to adapt to the pre-defined laminagon cycle of the PV modules Ø Enhance the creeping resistance of the encapsulant

13 BIPV elements Coloured and reliable ü EncapsulaGon & laminagon process ü Coloring technics on glass and plasgc ü General system view ( energy management) ü ClimaGc chamber for IEC tesgng and more ü ExperGze in design & architecture ü Architectural integragon ü Customized products ü Ultra-reliable ü Easier implementagon of PV in buildings ü Bener societal acceptance of PV

14 BIPV elements The white PV modules A reduc(on of around 10 C at the back of the module is measured when outdoor temperature is at 25 C.

15 White and coloured Efficient spectral selectivity
