Overview

Quantum-chemical modeling highlights charge separation efficiency at pbdb-t:itic interfaces, suggesting ways to enhance photovoltaic parameters.

Key Points

  • Charge trapping occurs in nearly half of the studied dimers, reducing charge separation efficiency and increasing recombination.
  • Significant differences in exciton-binding energies are noted when comparing B3LYP and HSE06 hybrid functionals.
  • Electronic properties are calculated using density functional theory and time-dependent DFT applied to various dimers.
  • These findings emphasize the importance of optimizing device performance based on the electronic characteristics of pbdb-t and itic.
