The effect of acid treatment of PEDOT:PSS anode for organic solar cells

Abstract

The goal of this paper is to develop and investigate the properties of PEDOT:PSS layer, which was treated with different acids and solvents including formic acid, sulfuric acid, and hydrochloric acid, methanol, acetone, and dichlorobenzene:methanol, to substitute ITO anode in organic solar cells. Organic solar cells structures were constructed with three different bottom electrodes: ITO, pure PEDOT:PSS and treated PEDOT:PSS. Two point probe method was used to measure resistance of pedot:pss layer were carried out and the best chosen method was employed to make an organic solar cell device.
