To date, the best reported power conversion efficiency (PCE) of state-of-the-art single-junction polymer solar cells (PSCs) is ∼ 9–10% 7, 8, 9, which still lags behind those of the most efficient tandem cells, mainly due to the relatively small absorption overlap with the solar spectrum.
In conclusion, we have demonstrated highly efficient single-junction PSCs with PCEs exceeding 10%, representing an important step towards the realization of economical solar cells with a high efficiency that is comparable with those of the best amorphous/microcrystalline Si solar cells or the best organic tandem cells reported to date.
