Capture more energy with EcoGuard EcoGuard Mo Molybdenum conductive glass Optimize CIGS and CIS photovoltaic modules. EcoGuard Mo is designed to increase the conductive properties of semiconductors made from copper indium gallium diselenide (CIGS) and copper indium sulfide (CIS). Optimize EcoGuARd Mo for Your technology Choose from varying sheet resistance options Custom-design a layer stack or work with us for custom thicknesses Combine with EcoGuard Barrier to control sodium migration and moisture Manage thin-film stressors with a tailormade stress-reducing layer PERFORMANCE BenefiTS Increase the output of CIGS and CIS photovoltaic modules Minimizes electrical barrier for enhanced conductivity Optimized for improved laser-scribing PRoduCT AvailABility Multiple grades of sheet resistance Thickness options: 2.1 mm, 3.0 mm, 3.2 mm and 4.0 mm (+/- 0.2 mm tolerances) Varying sizes are available with length and width tolerances of +/- 0.1 mm Edge work options for seaming or grinding (C-shape or K-shape) EcoGuard Barrier Sodium migration control Precision control. From complete sodium blocking, to allowing just the right amount of sodium migration, we can create a barrier coating optimized for the amount of sodium that your absorber needs to perform at its best. Prevent current leakage. Applied to the surface facing the outside of the solar cell, EcoGuard Barrier prevents current leakage by blocking moisture. Protection that retains high conductivity of energy and prevents water and humidity from detracting from your collected current: it all adds up to more energy over time for you to convert into valuable module output. Guardian experts are ready to help you select a custom combination of glass and glass coatings to get the most out of your technology. PERFormance benefits Controls sodium migration, leading to optimal production Blocks moisture, reducing current leakage and extending life cycle ProduCT availability & options Multiple thicknesses Edge treatments Custom cut-sizes with tight tolerances Combine with powerful EcoGuard options such as pattern, anti-reflective or specialized coatings to improve conductivity 3
EcoGuard Float AR and EcoGuard Pattern AR Anti-reflective solar glass EcoGuard Float AR and EcoGuard Pattern AR help you make the most of the available sunlight by reducing reflection and enabling you to capture light that would otherwise be lost.
