Fujian WuGouSuo organic inorganic hybrid biaxial ferroelectric photovoltaic materials research progress

Further, based on the biaxial characteristics, the compounds of the photovoltaic effect can be mutual transformation between multiple directions. Ferroelectric is a kind of important functional materials, it is the most distinct feature of the material inside the spontaneous polarization in the external conditions ( What pressure, silicon is a material field, light, etc. ) The change of direction. In recent years, organic inorganic hybrid perovskite because of its abundant physical properties, in the field of photovoltaic devices, storage, sensor has a broad application prospect. Related research results in the form of communications recently published in the journal of the American chemical society '( J。 点。 化学。 Soc。 , 2019, 141, 7693 - 7697). , a doctoral candidate in the king gave for the paper's lead author. At the same time, the compound unique symmetry broken ( 4/mmmFmm2） Make it has four equivalent polarization direction.

the study found that the compounds in organic and inorganic distorted octahedral cations of ordering synergy to induce the spontaneous polarization of ferroelectric compounds; Chinese Academy of Sciences, fujian institute of material structure of state key laboratory of structural chemistry inorganic photoelectric functional crystal materials researcher Luo Junhua team in key project of national natural science funds, solar much of national outstanding youth fund, special strategic leader of the Chinese Academy of Sciences and the national natural science foundation of China youth fund funding, such as building a case for the first time two dimensional three layers of organic inorganic hybrid biaxial ferroelectrics. Photovoltaic components cost of the work is not only designed for scientific research personnel subsequent multi-axis ferroelectric material provides a new strategy, and further development of inorganic organic hybrid multi-axis ferroelectric photovoltaic performance research. Compared with uniaxial ferroelectrics, solar much multi-axis ferroelectrics with multiple equivalent polarization direction of polarization reverse it easier. Bookcase against the wall and the back, however, it is based on hybrid perovskite implementation with photovoltaic effect of multi-axis ferroelectrics is still one of the important problems need to be solved.
