The Synthesis And Characterization Of Several Kinds Of HTMs

Organic/Inorganic hybrid perovskite material is the crystal material consisting of orderly self-assembled organic and inorganic molecules and having quantum well structures. It has drawn much attention for its advantages such as mechanical stability, thermostability of inorganics and good workability, functionality of organics with high carrier mobility and also has shown excellent property in the direction of light and electricity. Although the perovskite solar cells containing just above-mentioned inorganic coatings have certain photoelectric conversion efficiency, the addition of organic layers (HTMs) will greatly improve the battery efficiency. Hence, study on the categories and functions of HTMs is the important means to improve efficiency as well as an indispensible process.On the other hand, the dye-sensitized solar cells, a strong competitor of hybrid perovskite, have gained much importance in contemporary energy research. The organic photosensitizers of the dye-sensitized solar cells consist of three different parts (D-π-A). The major and most important part of the organic photosensitizers about electron transfer is the π-conjugated structure whose performance will determine the cell efficiency directly.In this paper, we synthesized two kinds of π-conjugated structure with a cheap raw material. Meanwhile, we also designed and synthesized three kinds of derivatives of diphenylamine replaced by different kinds of alkoxy chains and then synthesized five kinds of hole-transporting materials similar to spiro-OMeTAD. Moreover, we characterized the structure of the products with MS and 1H NMR, etc.
