    • Flexible light weight solar cell laminates: Dr. Gert Jan Jongerden Helianthos bv company confidential
    • Helianthos – light weight flexible solar laminates  Our Star: the SUN  Thin Film Solar Cells  Light weight thin film solar laminates  Helianthos • Product & Technology • Application and Market • Next steps  Outlook and Conclusions Helianthos solar cells foil 2
    • Our star: The SUN • Solar irradiation - On the earth surface ~ 1000 W/m2 - Irradiation 800 – 2500 kWh/m2.yr - Capacity factor ~8000 (= yearly irradiation/annual primary energy consumption) - Even for medium eff. solar cells (9%) in Netherlands : 3500 kWh per year with < 50 m2 solar cells sufficient for an average household 3
    • SOLAR ENERGY (direct conversion) Solar Thermal Photovoltaic (PV) Concentrated Solar Power = heat from sunlight direct conversion of (CSP) (solar collector) light into electricity … in sunny deserts Thin film PV solar modules wafer based cells Future technologies (glass panels & Flat plate & concentrator nanolayers / ‘solar paint’ flexible laminates 4
    • Thin film solar cells protective layer TCO - transparent front contact electron active layer hole back contact substrate 5

    • Helianthos solar cells foil 8
    • Highly attractive for applications and markets requiring light weight and flexibility  Industrial roofs, BIPV (building integrated PV)  Mobile/ automotive  Functional textiles  Military/ outdoor  Consumer applications  Rural / remote habitation 9
    • Objective: cost competitive solar electricity using integration in building materials and easy installation Module efficiency % kWh costs ↓ Today main solar tech c-Si wafer System Costs (€/Wp) ↓ Helianthos Module costs ↓ + System integration costs ↓ Cost * € /kWh Solar cell laminate products:  Roll-to-Roll production technology  Flexible & lightweight modules  Thin film silicon technology: abundant, robust  Pilot: a-Si single cells PV laminate  Future production: a-Si/µc-Si tandem cells PV laminate Saving materials, continuous processes, simple installation & combining functions 10

    • Value chain Helianthos PV-laminate Helianthos Helianthos distribution Building Integrated PV-laminate installable products installation PV Helianthos light weight solar cell laminates address the large (separate) market of BIPV & industrial roofing 27
    • Market development favorable for cost efficient rooftop and BIPV products Source: EPIA , EUPD, Accelios 28
    • Helianthos self-adhesive flexible solar cell foil for integration on: Bituminous roofing PVC/ TPO/ EPDM roofing Metal roofing panels  Various self adhesives (stick and peel), tuned and certified to be used in combination with different roofing materials and roofing materials manufacturers • with or without use of a roofing primer • on existing roofs with a good surface quality and > 25 years lifetime expectancy or newly placed roofs • As a BIPV or BAPV system 29
    • Helianthos’ next milestone is a production factory • Next steps: • achieve milestones • attract investment partner • gradual expansion to (tandem) volume production 30
    • Summary  Light Weight flexible thin film solar laminates • Combining energy & building functions for competitive kWh costs • Thin film silicon: a species with survival ‘genes’  Helianthos : • Proprietary roll-to-roll thin film silicon product & technology • Product fit for volume market: BIPV/large roofs & integration • Growth opportunity for value creation Helianthos solar cells foil • Preparing next step: inviting investment partner(s) 31
