Glazing that generates electricity In theory and practice Agenda: o ASI technology o Efficiency o The product o Reference projects
ASI Technology Generating electrical power with sunlight
Efficienty Solar radiation roof and facade The optimal energy yields are achieved when the system is facing the south at an angle of approx. 35 to the horizontal (100). Alignments that deviate from this will produce somewhat lower yields
Partition energy yield for Glasgow/Oslo/Copenhagen Absolute value: 30 south: 828 kwh/kwp 90 south: 531 kwh/kwp
Steps thin film production Glass Substrate Flow process 1: Coating and structuring Start: Glass with transparent conductive coating Step 1: Creating a structure with laser Step 2: Application of the semiconductor Step 3: Creating the semiconductor structure with laser Step 4: Application of the metallic backside Step 5: Creating the metallic backside structure with laser Step 6: Creating transparent lines with laser Flow process 2: cutting electrical contact - flashing Delivery Step 7: Cutting raw glasses Step 8: Applying wiring and electrical contact Step 9: Flashing performance test SCHOTT ASI TM THRU thin film module

Glazing that stores energy Agenda: o PCM technology o Efficiency o The product o Reference projects
Heat storage within the glass facade Glass build up: Base option: Plastic container considing a PCM placed within a DGU Add ons: Triple glazing to reduce the U-value further Quadruple glazing to integrate a prismatic layer to reflect direct sun light and to optimize the storage capacities
Heat storage within the glass facade The MAGIRA crystal can provide a high insulation value plus external sun protection whilst creating a comfortable day light situation within the building. The transluzent glass brings diffuse day light into the interiour and stores the solar heat during the day whilst releasing it during nighttime. Evening: PCM is liquid, storage capacity full Night: beginn of cristallization Morning: fully cristalized, max. storage capacity available
SCHOTT MAGIRA crystals the wall element glass Transparent Energy Storage System Increases Amount of natural daylight Increases thermal mass Allowing higher glazing ratios in the south facing facades Maintenance free Design freedom in the choice of glass within the system
