Abstract

The first homo-tandem non-fullerene organic solar cell enabled by a novel recombination layer which only requires a very mild thermal annealing treatment is reported. The best efficiency achieved is 10.8% with a V<sub>oc</sub> over 2.1 V, which is the highest V<sub>oc</sub> for double-junction organic solar cells reported to date.
