An efficient perovskite solar cell with symmetrical Zn(II) phthalocyanine infiltrated buffering porous Al2O3 as the hybrid interfacial hole-transporting layer
• A new Zn(II) phthalocyanine (Pc) based low bandgap HTM is introduced for perovskite solar cells. Steady state and time-resolved photoluminescence (PL) measurements indicated an evenly matched hole extn. efficiency between sym-HTPcH and spiro-OMeTAD. On account of the low film quality and resulting high recombination, Zn(II) Pc normally cannot work as an effective HTM. We adopted insulating Al2O3 for the infiltration of sym-HTPcH to form a hybrid interfacial buffer layer, affording perovskite solar cells (PSCs) with an av. PCE value of up to 12.3%, which is a significant improvement with res...
