Abstract

Abstract : An N719 based high‐efficiency binary cathode buffer layer (CBL) was developed. The work‐function of the Al cathode was precisely modulated between −3.3 and −3.9 eV due to the cation re‐arrangement between the binary components, induced by finely controlling the binary‐components weight ratio. A 10.50%‐ and 11.46%‐efficiency organic solar cells were reported with the use of the N719 and the binary CBL, respectively. Abstract : A new story of N719 : Herein, the old and famous dye, N719, was utilized as high‐efficiency, alcohol solution‐processible cathode buffer layer (CBL) material. N719 and the binary N719:PrC60MAI CBL, respectively, affords 10.50%‐ and 11.46%‐efficiency, single‐junction ternary polymer solar cells. The work function of the Al cathode can be modulated between −3.3 and −3.9 eV simply by controlling the binary components weight ratios, which is due to the weight‐ratio‐dependent re‐arrangement between the four kinds of cations and anions.
