Now introduce a scientific discovery about this category, Name: 2,5,8,11,14-Pentaoxapentadecane.
Simple and Efficient Perovskite Solar Cells with Multi-Functional Mixed Interfacial Layers
Recently, hybrid organic-inorganic perovskite solar cells (PVSCs) have attracted significant attention owing to their simple solution processability and high efficiency for the next generation of low-cost solar cell technology. Herein, a multi-functional interfacial layer (IFL) composed of a mixture of poly(oxyethylene tridecyl ether) (PTE) and ethanolamine (EA) is introduced between a CH3NH3PbI3 perovskite light-absorbing layer and a nickel oxide (NiOx) hole transport layer to improve the photovoltaic (PV) performance of PVSCs. With the solution-coated IFL of mixed PTE:EA, a highly improved film-forming capability of the perovskite layer is realized together with large-sized grains and fewer film defects. Moreover, the IFL also improved the charge carrier separation and hole-extraction capabilities at the interface between the CH3NH3PbI3 and the NiOx layers. The results here successfully demonstrate that the CH3NH3PbI3 PVSC with IFL exhibits greatly improved PV performance, in this case a much higher power conversion efficiency (15.1%), greatly exceeding that (12.3%) of a reference device without an IFL. The author’s study demonstrates that a multi-functional mixed IFL can be used as a solid foundation for efficient and cost-effective PVSCs, thus providing a platform for the realization of a new generation of highly efficient solution-processable PVSCs.
