The application of Novaled materials to solar cells allowes for highest efficiencies, just the way it does for OLEDs. It allowes easy integration of tandem architecture (stacking of two solar cells on top of each other) with excellent performance:
5% efficiency (1cm² active area, Heliatek tandem architecture
based on Novaled p- and n-dopants combining absorber
materials from Heliatek and BASF)
High open circuit voltage (1.9V)
High fill factor (60%, improved fill factor with NDP9)
Lifetime for pin-type Heliatek solar cells with Novaled
dopants: up to 16.000h (exposed to 100mW/cm² white light),
very good thermal stability.
Use of doped transport layers allowes for optical engineering and thus for optimized efficiency. Novaled technology is proven for highest OLED stability and this also holds for organic solar cells.
