Cu(II) and Zn(II) based Phthalocyanine as Hole selective layers for Perovskite Solar Cells

Abstract

Recently, significant progresses have been achieved in the fabrication of highly efficient perovskite solar cells, while major challenges, such as commercial viablity of exoctic materials and their instability, remain as an obstacle. Hole transporting materials (HTMs) represent a tricky choice for the fabrication of efficient solar cells and the cost uneffective Spiro-OMeTAD continue to be so far the most obvious candidate. Organometalic complexes, such as phthalocyanine metal complexes appeared as a promising class of p-type material, since they are less expensive and more stable. Herein, we report the synthesis of a novel Cu(II)-based phthalocyanine ((tOctPhO)8CuPc 1) with 4-tert-octylphenol-substituted function groups that possesses a very good solubility in a wide range of organic solvents, and thus can be applied from solution processing in a wide range of electro-optical devices. In the present work (tOctPhO)8CuPc 1, and its Zn(II) analogoes phthalocyanine (represented as (tOctPhO)8ZnPc 2) were tested in mixed perovskites (FAPbBr3)0.85(MAPbI3)0.15 for the fabrication of perovskite solar cell. These phthalocyanine based HTMs gave competetive power conversion efficiencies and demonstrated superior stability when compared to classical HTMs.
