Description

Tris-PCBM – SOL5063

CAS: N/A

Tris-PCBM is a derivative of Fullerene C60 with a LUMO level closer to the vacuum, resulting in a potential reduction in energetic losses associated with electron transfers from the donor material, providing a potential Voc increase in blends of donor:fullerene-based OPV systems.

Used as an electron acceptor from Donor materials such as P3HT (SOL4106), PCDTBT (SOL4280), or PTB7 (SOL4700) to make high Open Circuit Voltage (Voc), high Power Conversion Efficiency (PCE) bulk heterojunction solar cells, >99.9% [6,6] isomerized.. Available for large-scale projects.

 

The Tris-PCBM (SOL5063), or tris[60]PCBM, is a highly functionalized C60 fullerene derivative representing the frontier in energy level engineering for organic photovoltaics (OPV). As a leading manufacturer of advanced electronic materials, Solaris Chem provides the SOL5063 specifically for researchers aiming to minimize charge transfer energy losses and reach the theoretical limits of Open Circuit Voltage (Voc).

Unlike standard PC61BM (mono-adduct) or even Bis-PCBM, the Tris-PCBM incorporates three functional groups onto the carbon cage. This significantly alters its optoelectronic properties and its behavior within the active layer of organic electronic devices.

The Tris-Adduct Advantage: Elevating the LUMO Level

The primary technical motivation for implementing SOL5063 in a device architecture is the precise manipulation of the LUMO (Lowest Unoccupied Molecular Orbital) level.

  • Reduction of Energetic Losses: In organic photovoltaics, each adduct added to the C60 cage pushes the LUMO energy level closer to the vacuum. Tris-PCBM features a LUMO level of -3.6 eV, which is significantly higher than that of standard PC61BM (approx -3.9 eV).

  • Voltage Maximization: The $V_{oc}$ of a solar cell is intrinsically linked to the energetic offset between the HOMO of the donor polymer and the LUMO of the fullerene acceptor. By elevating the LUMO with Tris-PCBM, the voltage potential of the cell is directly increased.

  • Ideal for Wide-Bandgap Donors: It is particularly effective when paired with donor materials that exhibit deep HOMO levels, where conventional acceptors would otherwise lead to excessive voltage drops.

Applications and Compatibility in OPV Systems

The Tris-PCBM (SOL5063) is a critical component in studies of energetic disorder and charge transport (as documented by Nelson et al.). It is a key material for:

  1. Bulk Heterojunction (BHJ) Solar Cells: Where fine-tuning the energetic cascade is required to maximize overall power conversion efficiency (PCE).

  2. Tandem Cell Architectures: Acting as a selective acceptor to optimize the performance of specific sub-cells.

  3. Photophysics Research: Used to study exciton dynamics and charge recombination at organic interfaces.

This material offers exceptional synergy with common donor polymers available at Solaris Chem:

  • P3HT (SOL4106): To achieve higher voltages in the classic reference architecture.

  • PCDTBT (SOL4280): Optimized for maximizing performance in high-stability device architectures.

  • PTB7 (SOL4700): Ideal for research into inverted architectures aiming to break efficiency records.
