PCBM (PC61BM / SOL5061) – Benchmark Electron Acceptor for OPV
PCBM (PC61BM, CAS: 160848-22-6), or [6,6]-phenyl-C61-butyric acid methyl ester, is the industry-standard electron acceptor in organic photovoltaics (OPV) and flexible electronics. Manufactured by Solaris Chem with >99.9% [6,6] isomer purity, SOL5061 overcomes the solubility limitations of pristine fullerenes to enable high-efficiency solution-processed bulk heterojunction (BHJ) solar cell fabrication.
Why SOL5061 is Essential for Organic Electronics
Compared to standard fullerenes, PC61BM (SOL5061) provides crucial processing advantages:
- Superior Solubility: Highly soluble in chlorobenzene, dichlorobenzene, and toluene, allowing for printable solar cells and large-area flexible electronics.
- High Electron Mobility: Facilitates rapid charge separation and transport within the active layer blend.
- Optimized Film Morphology: Forms well-defined nanoscale domains when blended with donor polymers to maximize exciton dissociation.
Available High-Purity Grades (SOL5061 Series)
- Grade > 99.00% (SOL5061B): Ideal for baseline testing and general laboratory R&D.
- Grade > 99.50% (SOL5061A): Standard choice for high-performance device optimization.
- Grade: 99.90% (SOL5061Z): Premium grade for high-efficiency solar cell records.
- Grade: 99.95% (SOL5061Y): Ultra-high purity for fundamental physical studies and sensitive architectures.
Synergistic Compatibility with Donor Materials
To maximize Power Conversion Efficiency (PCE) and Open Circuit Voltage (Voc), SOL5061 is optimized for pairing with key donor polymers:
- P3HT (SOL4106): Classic benchmark for stable, cost-effective organic photovoltaic research.
- PCDTBT (SOL4280): Polymer engineered for increased thermal stability and high voltage output.
- PTB7 (SOL4700): Frequently utilized in high-efficiency inverted solar cell architectures.
