Current perovskite solar cells (PSCs) intended for commercialization in the near future require both high efficiency and good long-term stability. Most highly efficient PSCs utilize an n-type layer of mesoporous titanium dioxide in an n-i-p device configuration, in which organic conductors are widely used to transport holes into an adjoined metal. Thus far, a variety of efforts have been devoted to achieve a defect-less perovskite film with high-quality morphologies to realize reduced loss-in-potential outcomes and enhanced efficiency levels. Furthermore, it is crucial to finely optimize an energy level matching between the perovskites and hole-transporting materials (HTMs) for achieving a better performance. In this presentation, I will talk about the efficient hole-transporting materials based on pyrene arylamine and spiro-OMeTAD derivatives. Our results showed that chemical engineering leads to a remarkable improvement of the inorganic-organic hybrid solar cells. |
