摘要：

The novel triplet-triplet annihilation ( TTA) upconversion (UC) field of rubrene (Rub) and dibenzo-tetraphenylperiflanthene (DBP) sensitized by bulk metal halide perovskite, integrated with copper-2,3, 9,10,16,17,23,24-octafluorophthalocyanine (F8CuPc) as cosensitizer, have been investigated in perovskite solar cells (PVSCs) to minimize sub-bandgap photon transmission loss. The firm hydrogen bonding interaction (F center dot center dot center dot H-N between F8CuPc and MA(+)), cation- p interaction (MA+ with Rub), and the hydrophobic characteristic of additives enable F8CuPc:Rub: DBP dually-sensitized p-i-n PVSCs based on MAPbI(3) and Cs-0.05(FA(0.83)MA(0.17)) Pb-0.95(Br0.17I0.83) (3) absorbers to attain champion efficiencies of 20.83% and 21.51%, respectively. Furthermore, due to the excellent photochemical and thermal stability of F8CuPc, the corresponding PVSCs can maintain nearly 80% of the original efficiencies exposed to air with 50 similar to 70% relative humidity over 1100 h and N-2 at 85 degrees C for 300 h.
