ABSTRACT
Organic solar cells (OSCs) with high performance were prepared using poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate) (PEDOTPSS) and [2-(3,6-dibromo-9H-carbazol-9-yl)ethyl]phosphonic acid (Br-2PACz) double-layer films as the anode interface. By spin-coating a layer of Br-2PACz on PEDOTPSS to form a PEDOTPSS/Br-2PACz dual-anode interface, both the Jsc and FF of the device can be increased simultaneously, resulting in a high Jsc of 27.84 mA cm-2 and a high FF of 78.18%. The promising result indicates that the PEDOTPSS/Br-2PACz dual-anode interface is an effective way to improve the performance of OSCs. The improvement of device performance is mainly attributed to (1) improved interface conductivity; (2) increased hole mobility and more balanced carrier transport efficiency; and (3) optimized morphology, which well explains the increase of Jsc and FF of the device. In addition, the OSC based on the PEDOTPSS/Br-2PACz dual-anode interface exhibits exceptional stability, as it can maintain 94.7% of its initial efficiency even after 500 h of storage in a nitrogen environment. This work provides a promising strategy for improving the efficiency and stability of OSCs by dual-anode interface modulation.
