Correlation of open-circuit voltage and energy levels in zinc-phthalocyanine: C₆₀ bulk heterojunction solar cells with varied mixing ratio
The maximum open-circuit voltage <em>V</em><sub>OC</sub> of bulk-heterojunction solar cells is limited by the effective HOMO(donor)-LUMO(acceptor) gap of the photoactive absorber blend. We investigate blend layers comprising zinc-phthalocyanine (ZnPc) and the buckminster full...
