Abstract

The invention provides an inorganic halogenated bismuth perovskite battery, comprising a transparent conductive substrate, an electron transport layer formed on the transparent conductive substrate, aperovskite light absorption layer formed on the electron transport layer, a hole transport layer formed on the perovskite light absorption layer and an electrode formed on the hole transport layer. The material of the perovskite light absorption layer is Cs2XBiY6, wherein X=Ag, Na, K or Rb, and Y=Cl, Br or I. A preparation method of the inorganic halogenated bismuth perovskite battery is furtherprovided, which is simple and easy to repeat. A fully inorganic perovskite light absorption layer with stable physical and chemical properties is used to replace the toxic lead component in the traditional perovskite light absorption layer, which not only improves the stability of the perovskite battery in the air, but also is beneficial to the industrial production of the efficient, stable and safe perovskite battery.

Description

technical field [0001] The disclosure relates to the technical field of optoelectronic materials and devices, in particular to an inorganic bismuth halide perovskite battery and a preparation method thereof. Background technique [0002] Perovskite cells have the advantages of low cost, high efficiency and strong plasticity, which has attracted great attention in the field of photovoltaic devices. At present, the notarized efficiency of single-junction cells has increased to 22.1%, surpassing the crystalline silicon cells that dominate the photovoltaic market. In addition, the efficiency of cells connected in series with silicon materials has exceeded 25%, and further optimization can reach 30%. Therefore, with the increase of photoelectric conversion efficiency and the development of industrial deposition technology, perovskite cells have broad application prospects in industrial production. However, organic perovskite light-absorbing materials such as CH 3 NH 3 PB 3 , ...
