제목 Modification of Pyridine Based Cathode buffer layer in Polymer Solar Cells
초록 Interfacial materials are essential to the performance and stability of polymer solar cells (PSCs). Here, we introduced the role of pyridine derivative as an efficient cathode buffer layer between the photoactive layer and Zn cathode. The work function of the cathode and energy barrier at the interfaces between the cathode and active layer was modified by changing interfacial dipole as different positions of hydroxide in pyridine. When using pyridine derivative instead of the traditionally used ITO/ZnO cathode in PSCs, the short-circuit current density (Jsc) is improved and the power conversion efficiency (PCE) of PSCs based device with pyridine buffer layer is increased. A better performance with PCE of different position is achieved when 2-hydroxy pyridine is chosen as buffer layers. The results indicate that pyridine derivative is a promising electron collection material as a substitute of the traditional low-work-function cathode.
