  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • Interface engineering plays an important role in performance improvement for bulk-heterojunction organic solar cells
  • We present a kinetic Monte Carlo study to clarify the role of the disorder at the D:A interface and the interface between the photoactive layer and the extraction layer on the performance of bulk-heterojunction OSCs
  • Our results demonstrate that the disorder at the D:A interface especially tailors the photocurrent and fill factor, while the disorder at the extraction layer mainly controls the open-circuit voltage
  • The D:A interface plays the dominant role in device performance and needs to be controlled to achieve efficient OSCs
