Empirically, device fabrication parameters are known to play a role in determining the PCE of OPV devices. The same can be observed in our dataset. The most common donor and acceptor combination is PBDB-T and ITIC with 11 occurrences. The PCEs of the PBDB-T:ITIC devices range from 7.3% to 11.2%, a significant difference for top-performing devices in different papers.
