Published in 2023 at "Advanced materials"

DOI: 10.1002/adma.202302452

Abstract: Organic solar cells benefit from non-fullerene acceptors (NFA) due to their high absorption coefficients, tunable frontier energy levels and optical gaps, as well as their relatively high luminescence quantum efficiencies as compared to fullerenes. Those… read more here.

Published in 2024 at "Small"

DOI: 10.1002/smll.202405201

Abstract: In organic-inorganic hybrid perovskite solar cells (PSCs), hydrogen defects introduce deep-level trap states, significantly influencing non-radiative recombination processes. Those defects are primarily observed in MA-PSCs rather than FA-PSCs. As a result, MA-PSCs demonstrated a lower… read more here.

Published in 2025 at "Small"

DOI: 10.1002/smll.202508481

Abstract: Non-radiative recombination is a key factor restricting photocatalytic efficiency, which leads to the rapid annihilation of photogenerated carriers through deep-level defect centers. Shallow-level defects can suppress non-radiative recombination through a unique carrier capture-release mechanism. Herein,… read more here.
