Flexible photovoltaics: next generation high efficiency and low cost thin film silicon modules

Abstract (English)

The objective of the project is the development of flexible photovoltaic modules with high efficiency. We propose the introduction of a new back reflector structure incorporating diffusely scattering surfaces which enhance the light path inside the thin silicon layers, assisted by a dielectric mirror which boosts the reflective properties. In parallel, area losses of the module interconnection will be substantially reduced by the development of a tandem structure. The goal of the project is to demonstrate a process suitable for the fabrication of 6% reliable flexible modules
