Photovoltaics (PV) (Amorphous (thin-film))
Advantages *Significant material and energy savings d*Significant material and energy savings during production due to direct application of the material onto the backing layer, which is made of glass, metal or plastic. *Technical advantage as the cells use diffuse or poor sunlight more efficiently *Less susceptible to cloudy weather *Higher shape flexibility *Translucent and shadow-giving *Flexible usage as a ventilated curtain-wall façade or an insulating glass façade / overhead glazing *Usage without restrictionshead glazing *Usage without restrictions  +

Description Thin-film photovoltaic cells are second geThin-film photovoltaic cells are second generation solar modules where thin films of photovoltaic material is deposited on a substrate, this films are 50 to a 100 times thinner than human hair and as efficient as the bulkier thick-film solar cells. Thin-film photovoltaic cells can produce up to 60 kWh of electric energy per square meter per year. In addition, as part of the facade, this state-of-the-art technology can be integrated seamlessly into a new building. Amorphous silicon, the material usually used for producing thin-film photovoltaic cells, is applied as a thin coating onto a glass panel through plasma processing. Weighing 20 to 30 mg/m², these thin-film modules are significantly lighter than the usual wafer-based modules, which can weigh up to 1kg/m². Moreover, thin-film photovol-taic cells have a greater energy efficiency compared to crystalline modules. Accordingly, they continue to produce electricity in indirect sunlight and are only marginally temperature-sensitive. Even at an inclination angle of under ten degrees, they maintain their full potential.
