Description
Tris-PCBM (SOL5063) – High LUMO Fullerene Trisadduct for Voltage Maximization
Tris-PCBM (SOL5063), or tris[60]PCBM, is a highly functionalized C60 fullerene trisadduct engineered to minimize charge transfer energy loss in organic photovoltaics (OPV). Supplied by Solaris Chem with >99.9% [6,6] isomer purity, SOL5063 features an elevated LUMO energy level (−3.6 eV) that significantly increases open-circuit voltage (Voc) in bulk heterojunction (BHJ) solar cells and tandem cell architectures.
The Tris-Adduct Advantage: Elevating the LUMO Level
- Reduction of Energetic Losses: Incorporating three adducts onto the carbon cage pushes the LUMO level to −3.6 eV (compared to ~ −3.9 eV for mono-PCBM), substantially reducing energetic drops during electron transfer.
- Voltage Maximization: Directly broadens the energetic gap between the donor polymer HOMO and fullerene LUMO, pushing open-circuit voltage (Voc) toward its theoretical ceiling.
- Ideal for Wide-Bandgap Donors: Delivers exceptional performance when paired with deep-HOMO donor polymers where conventional acceptors cause excessive voltage loss.
Available High-Purity Grades
- Grade > 99.50% (SOL5063A): Standard high-purity trisadduct grade for device optimization and photophysics testing.
- Grade > 99.90% (SOL5063B): Ultra-high purity trisadduct grade for record-setting efficiency attempts and precise interface studies.
Applications & Donor Compatibility in OPV Systems
Tris-PCBM (SOL5063) is a vital benchmark material for studying energetic disorder and charge transport in:
- Bulk Heterojunction (BHJ) Solar Cells: Fine-tunes the energy cascade to maximize power conversion efficiency (PCE).
- Tandem Cell Architectures: Functions as a selective acceptor layer to balance voltage and current across sub-cells.
- Photophysics & Interface Research: Utilized to analyze exciton dynamics and suppress charge recombination.
Optimal Pairing with Solaris Chem Donor Polymers:
- P3HT (SOL4106): P3HT polymer for achieving higher voltages in classic benchmark architectures.
- PCDTBT (SOL4280): PCDTBT polymer optimized for maximum stability and high voltage output.
- PTB7 (SOL4700): Ideal for inverted cell architectures aiming to minimize energy loss.

Frequently Asked Questions (FAQ) – Tris-PCBM (SOL5063)
What is the primary technical advantage of Tris-PCBM (SOL5063) over mono- and Bis-PCBM?
Tris-PCBM incorporates three functional groups onto the C60 carbon cage, pushing its LUMO energy level closer to the vacuum (-3.6 eV vs -3.9 eV for mono-PCBM). This significantly reduces energetic voltage loss during electron transfer and directly increases the open-circuit voltage (Voc) of organic photovoltaic devices.
Which donor materials offer optimal compatibility with Tris-PCBM?
Tris-PCBM is ideal for pairing with wide-bandgap and deep-HOMO donor polymers, including P3HT (SOL4106), PCDTBT (SOL4280), and PTB7 (SOL4700), to maximize energy cascade efficiency in solar cells.
In what advanced OPV architectures is Tris-PCBM primarily used?
Tris-PCBM is extensively utilized in bulk heterojunction (BHJ) solar cells, tandem solar cell sub-layers, and photophysics research focusing on exciton dynamics and charge recombination minimization.
