The development of solution processible charge-transporting materials are very important because these materials can efficiently extract charge carriers from the active layer to the electrodes and are compatible with multi-layer fabrication process to help realize the full promise of thin-film solar cell technology for low-cost and scalable renewable energy.In this presentation,we introduce the development of several new types of conductive electron-transporting layers(ETLs)by systematically integrating multiple functions into the new material systems.Conductive,stable,and solvent resistant ETLs were developed to address the following challenges:(1)development of stable,solution-processible n-doped organic π-functional materials;(2)understanding of the underlying n-doping mechanisms;(3)introduction of crosslinking chemistry to form robust charge-transporting layers for multilayer integration.The charge extraction and energy alignment of ETL are simultaneously optimized due to enhanced conductivity and stability of new ETL,which afford high efficiency devices and long lifetime.These materials can be applied to broad organic electronic applications.
