Crystalline photovoltaic glass

Crystalline silicon photovoltaics is the most widely used photovoltaic technology. Crystalline silicon photovoltaics are modules built using crystalline silicon solar cells (c-Si). These have high efficiency, making crystalline silicon photovoltaics an interesting technology where space is at a premium.

To meet specific requirements, we offer two advanced photovoltaic (PV) glass technologies: amorphous silicon and crystalline silicon, both fully customizable. Our glass can be customized to block the heat that enters the building and to provide the best insulation, thus avoiding the use of air conditioning and heating.

Crystalline silicon solar cells are connected together and then laminated under toughened or heat strengthened, high transmittance glass to produce reliable, weather resistant photovoltaic modules. The glass type that can be used for this technology is a low iron float glass such as Pilkington Optiwhite™.

Our photovoltaic glass offers a cutting-edge solution for both new construction and renovation projects. When integrated into ventilated façades, this glass enhances building aesthetics while providing key benefits such as radiation protection, thermal and acoustic insulation, and improved occupant comfort.

The active photovoltaic layer, responsible for converting solar energy into electricity, is composed of semiconductor materials. In crystalline silicon-based PV glass, this layer contains ultra-thin silicon wafers, while thin-film technologies utilize materials such as amorphous silicon, cadmium telluride, or copper indium gallium selenide (CIGS).

In optimal conditions, modern PV glass installations typically achieve conversion efficiencies ranging from 5% to 15%, with high-end products reaching up to 20% efficiency. Real-world performance data indicates that a standard square meter of PV glass can generate between 50-200 kilowatt-hours (kWh) annually.
