Popis: | Organic solar cells (OSCs) have reached a milestone with 15.6% efficiency through the development of active and interfacial materials. However, anode modifiers in the inverted structure, especially the interface of organic active layer/inorganic MoO3, are important but seldom reported. Herein, to improve this contact, a simple small molecule DPA2T with oligo-oxyethylene chains is reported. It not only shows a good solubility in alcoholic solvents but also an effective π-π stacking in solid-state. Furthermore, the implement of DPA2T in OSCs enhances the fill factor and the short circuit current resulting in an improvement of the overall power conversion efficiency. |
