Re-evaluating the Role of Sterics and Electronic Coupling in Determining the Open-Circuit Voltage of Organic Solar Cells

The effects of sterics and molecular orientation on the open‐circuit voltage and absorbance properties of charge‐transfer states are explored in model bilayer organic photovoltaics. It is shown that the open‐circuit voltage correlates linearly with the charge‐transfer state energy and is not signifi...

Zusammenfassung:The effects of sterics and molecular orientation on the open‐circuit voltage and absorbance properties of charge‐transfer states are explored in model bilayer organic photovoltaics. It is shown that the open‐circuit voltage correlates linearly with the charge‐transfer state energy and is not significantly influenced by electronic coupling.
