Efficient Low-Bandgap Polymer Solar Cells with High Open-Circuit Voltage and Good Stability

Efficient Low-Bandgap Polymer Solar Cells with High Open-Circuit Voltage and Good Stability

A novel D‐A1‐D‐A2‐type polymer that exhibits a small bandgap of 1.43 eV yet still yields polymer solar cells with a high open‐circuit voltage (VOC) of 0.81 V and power conversion efficiencies of up to 8.63% is reported. Comparable efficiencies can be achieved even when the active layer is processed...

Zusammenfassung:A novel D‐A1‐D‐A2‐type polymer that exhibits a small bandgap of 1.43 eV yet still yields polymer solar cells with a high open‐circuit voltage (VOC) of 0.81 V and power conversion efficiencies of up to 8.63% is reported. Comparable efficiencies can be achieved even when the active layer is processed in air or after it is thermally annealed at 150 °C.
