Thin film has fundamental advantages over silicon PVWhy thin film?
Thin film module costs are lower and more stable than silicon
Thin film modules have a much shorter energy payback time
Thin film value chain is simpler
Thin Film value chain is, by nature, fully integrated

Avancis modules have shown the highest efficiency of any thin film technology: 20.3% record cell efficiency in the laboratory 15.5% record module aperture efficiency
(0.1m²) 11.0% average module area efficiency in fab
(1m²)
Since all thin film technologies have similar cost per unit area, the lowest cost per Wp will result from the technology with the highest efficiency.
Avancis gives most value for money.

Avancis PV modules : Best Solar Power for India
Avancis advantages Spectral absorption range is widest from 300-1300 nm (mono/poly/a-
Si cells ranges from 400-700 nm) 5-10% more energy generation than crystalline silicon modules. Better suited for hot countries than Cr- Si More energy generation than Cr-Si even in low light, cloudy or hazy
conditions. Produce consistent superior output (kWh/kWp) when tested in the
same natural environment Lower cost production as compared to Cr Si Contains no hazardous or environmentally toxic materials Versatile technology : easily applied in rooftops or fields Land requirement comparable to that of Cr-Si projects Aesthetics: The uniform solid black color of the panels has an
excellent appealing appearance Comes with the Credibility of Saint-Gobain name
