HeliaFilm® – Patented multilayer stack architecture

Heliatek is one of the leading manufacturer of energy generating solar films. The technology is based on carbon materials deposited in a unique roll-to-roll vacuum deposition process. The properties of the ultrathin organic photovoltaic film result in some truly unique product features of HeliaFilm®.

Heliatek’s competitive advantage are the fundamental patents covering the production of multilayer organic solar cells with doped transport layers. Using this proprietary architecture, it is possible to absorb a broad solar spectrum, using extremely thin layers. The active layers are only around 250 nm thin. The manufacturing process is completely free of toxic materials and rare earth elements enabling a scale-up without any restrictions.
