High-Efficiency Organic Solar Cells (OPVs)

OPV Device Structure: ITO/PEDOT:PSS/Polymer:PC71BM/ Al

• JSC = 19.8 mA/cm² \
• VOC = 0.79 V
• FF = 0.65
• PCE = 10.12%

PTB7-Th is mainly used as an active layer in organic solar cells (OSCs). It forms a blend with different acceptor materials which include PC71BM, ICBA, and PCBM to potentially improve the power conversion efficiency (PCE) of the OSCs.
