Perovskite solar cells (PSCs) have rapidly emerged as a highly promising photovoltaic technology, offering high efficiencies and the potential for low-cost manufacturing. A critical component in achieving efficient charge extraction in PSCs is the electron transport layer (ETL). Among the various ETL materials investigated, fullerene derivatives, particularly PC61BM, have played a significant role. This article explores the function of PC61BM in PSCs and highlights the importance of sourcing from reputable suppliers.

PC61BM: A Key Electron Transport Layer in PSCs

In a typical perovskite solar cell architecture, light absorbed by the perovskite layer generates electron-hole pairs. The electrons are then transported to the cathode, and the holes to the anode, via selective transport layers. PC61BM, with its favorable LUMO energy level, acts as an efficient electron acceptor and transporter. It forms a crucial interface with the perovskite absorber layer, effectively extracting electrons and preventing recombination. The high electron mobility of PC61BM allows for rapid electron transport, minimizing charge losses and contributing to the high power conversion efficiencies (PCEs) observed in many PSC devices.

Advantages of Using PC61BM in PSCs

Several factors make PC61BM an attractive choice for ETLs in PSCs:

  • Efficient Electron Extraction: Its energy level alignment with common perovskite absorber materials facilitates efficient electron extraction.
  • Good Solubility: Similar to its use in OPVs, the solubility of PC61BM in organic solvents allows for solution-based deposition of the ETL, which is compatible with low-cost fabrication methods.
  • Electron Mobility: PC61BM provides good electron mobility, which is essential for minimizing recombination and achieving high photocurrent.
  • Passivation Properties: Studies suggest that fullerene derivatives like PC61BM can also help passivate defects at the perovskite/ETL interface, further enhancing device stability and performance.

While newer ETL materials are continuously being developed, PC61BM remains a benchmark and a widely used material in PSC research. Its well-understood properties and availability make it a reliable choice for many research groups and commercial ventures.
