A new layered nano hybrid perovskite film with enhanced resistance to moisture-induced degradation

In this paper, a new layered hybrid perovskite film ((EDA)(MA)2[Pb3I10]) was synthesized through one-step method. Ethylenediamine (EDA) cation was introduced into the perovskite lattice to synthesize a layered structure with improved resistance to degradation by humidity. The effects of humidity and time on crystal structure, composition, morphology and absorption spectra of (EDA)(MA)2[Pb3I10] were analyzed by in situ grazing incidence X-ray diffraction (GIXRD), scanning electron microscope (SEM), and UV-Vis spectroscope. The results reveal that a (EDA)(MA)2[Pb3I10] film is more moisture resistant than a CH3NH3PbI3 film which is widely used in the perovskite solar cell now. UV-Vis spectroscopy result also shows that the layered structure film is a suitable solar absorber with a bandgap (1.67 eV), which is close to the optimum value for solar photoelectric conversion. Compared to CH3NH3PbI3, the low-cost perovskite structure offers greater tunability on a molecular level for further material optimization and possibility for widely used in the future.

Preparation method of ethanediamine dihydroiodide

The invention relates to the technical field of organic iodine compound synthesis and discloses a preparation method of ethanediamine dihydroiodide. The preparation method comprises orderly adding deionized water, ethene diamine and iodine elementary substance into a reactor according to a mass ratio of ethene diamine to iodine elementary substance of 58: 230-270, and gradually feeding hydrogen sulfide gas into the reaction system under the condition of stirring and a temperature of 40-50 DEG C, wherein when the color of reaction system is changed into faint yellow or achromatic color from dark black, the reaction is finished, filtering the reaction solution, carrying out atmospheric distillation on the filtrate until the unevaporated solution does not contain hydrogen sulfide gas, cooling the unevaporated solution, filtering the unevaporated solution until the solution is clear and carrying out cooling crystallization or evaporation crystallization to obtain the ethanediamine dihydroiodide. The preparation method utilizes cheap raw materials, has simple processes and is convenient for large-scale industrial production. The ethanediamine dihydroiodide is white, has high purity and a high yield, prevents hydroiodic acid use, reduces a raw material cost and an equipment cost and improves production safety.
