Solar applications

For building-integrated photovoltaics that replace roof and facade components, PV modules in a variety of possible colors are an attractive alternative to classic solar systems. SolarColor, which was developed by AGC Interpane and Fraunhofer ISE, has an efficiency of more than 90 percent despite its colored surface.

The MorphoColor® color layer is a photonic structure in which an interference layer is combined with a geometrically structured substrate in such a way that a particularly narrow-band reflection maximum is produced. As only small parts of the light spectrum are reflected, the remaining sunlight can pass through undisturbed. This reduces efficiency by less than 10 percent. SolarColor glass can also be used for building-integrated colored solar thermal collectors or PVT collectors.

Building-integrated photovoltaics (GIPV)

SunEwat is a laminated glass with embedded monocrystalline or polycrystalline photovoltaic cells – a component that actively produces electricity and thus significantly improves the energy balance of buildings.

The cells are installed between two toughened panes of glass. Ideally, the outer pane is made of particularly clear white glass to maximize the electricity yield. The inner pane can be clear, extra-clear, tinted, screen-printed or otherwise designed glass. The modules are connected to a photovoltaic system via a cable box. The cell spacing can be varied, and therefore also the light transmission of the module. If SunEwat is used in unventilated sandwich parapet cladding, it retains its performance even at high temperatures.

To provide architects with all the options for building integration, the modules are manufactured according to individual dimensions – for:

• Facades
• Glass roofs
• Canopies
• Parapets
• Further applications

The iplus HT anti-reflective coating makes the glass surface non-reflective and increases the energy transmission by 5 percent compared to uncoated glass – thus maximizing the solar energy yield. Another advantage is the low angle dependency of the coating, which significantly increases transmission in the morning and evening hours and during the low-radiation winter months.
