基于P3HT给体的单/双受体平面异质结电池性能及其介电特性
Performance and Dielectric Property of Single/Double Acceptor Based Planar Heterojuntion Organic Photovoltaic Cells with P3HT Donor
摘要
Abstract
To investigate the influence of interface charge on the performance of organic photovoltaic cells (OPVs),the single/double acceptor based planar heterojunction(PHJ) OPV based on P3HT donor were fabricated. Firstly,the effect of poly(3-hexylthiophene) (P3HT) film thickness,P3HT solvent,and the drying time of P3HT film on device performance was studied. To further improve the P3HT/SubPc PHJ performance, the cascade structure of ITO/PEDOT:PSS/P3HT/chloroboron (Ⅲ) subnaphthalocyanine(SubNc)/boron subphthalocyanine chloride(SubPc)/BCP/Al including double acceptors was fabricated,and the influence of SubNc thickness was also investigated. In the single acceptor system,by using the mixed solvent (V(chloroform):V(ODCB) =1:1) and drying in air for 10 min, the obtained P3HT film achieves the highest performance. While in the cascade structure, the power conversion efficiency (PCE) firstly rises then declines with the increase of SubNc thickness. When the SubNc thickness is 5 nm, the PCE is the highest. The photovoltaic parameters of cascade cell are all improved compared with the single acceptor based cells. Finally, to get insight into the physical mechanism between the interface charge and device performance,the effect of SubNc thickness on the dielectric characteristic of cascade cells was studied.关键词
