Description
Bis-PCBM (SOL5062) – High open-circuit voltage (Voc) Electron Acceptor
Bis-PCBM (SOL5062, CAS: 1048679-01-1), or [6.6] Diphenyl C62 bis(butyric acid methyl ester), is an advanced fullerene bisadduct electron acceptor engineered for organic photovoltaics (OPV). Supplied by Solaris Chem with >99.9% [6,6] isomer purity, Bis-PCBM provides a higher LUMO energy level (−3.6 eV) than standard mono-PCBM, enabling higher open-circuit voltage (Voc) and superior power conversion efficiency (PCE) in polymer solar cells.
Key Advantages of Bis-PCBM
- Enhanced Open-Circuit Voltage (Voc): A higher LUMO energy level (−3.6 eV vs −3.7 eV for mono-PCBM) reduces energetic loss to maximize cell Voc.
- High Isomer Purity (>99.9% [6,6]): Ensures consistent film morphology, reproducible domain separation, and efficient charge transport.
- Superior Organic Solubility: Soluble in common processing solvents like chloroform, chlorobenzene, toluene, and xylenes for solution-processed solar cells.
- Large-Scale Availability: Produced under strict Canadian quality control standards to support both R&D and industrial scale-up projects.
Available High-Purity Grade
- Grade > 99.50% (SOL5062A): Ultra-pure bisadduct grade optimized for high-efficiency solar cell fabrication and advanced research.
Synergistic Compatibility with Donor Materials
Bis-PCBM (SOL5062) is optimized for pairing with benchmark polymer donor materials to construct high-performance bulk heterojunction (BHJ) active layers:
- P3HT (SOL4106): Poly(3-hexylthiophene-2,5-diyl) for reliable, high-voltage baseline solar cell research.
- PCDTBT (SOL4280): PCDTBT polymer for high-voltage, thermally stable device configurations.
- PTB7 (SOL4700): High-efficiency donor polymer for advanced inverted photovoltaic architectures.
