Abstract

The invention relates to a perovskite battery model based on a TiO2 nanocone array. The perovskite battery model comprises a glass substrate, a tin oxide fluoride layer, a sub-wavelength TiO2 nanoconelayer, an MAPbI3 photosensitive layer and an Au electrode layer which are sequentially stacked from bottom to top. Through the novel cell structure design, light absorption of the solar cell is improved, the sensitive characteristic of the cell to the incident light angle is improved, charge extraction is improved, and the solar cell can be used as an ultrathin, semitransparent and flexible device.

Description

technical field [0001] The present invention relates to the field of novel battery technology, more specifically, relates to a TiO-based 2 A perovskite cell model of nanocone arrays. Background technique [0002] One of the current development directions of thin-film perovskite cells is to prepare flexible, wearable, translucent, stacked devices. At the same time, the reduction in the thickness of the active layer can also save the amount of perovskite materials used, reduce the amount of lead (Pb), and reduce the possible pollution risk to the environment. Therefore, ultrathin perovskite solar cells have received great attention. However, the ultra-thin perovskite layer also faces the problem of reducing the absorption of incident light, and it is necessary to increase the light absorption rate of the ultra-thin perovskite active layer. Introducing a two-dimensional patterned structure into thin-film perovskite solar cells (Perovskite Solar Cells, PSCs) to achieve high-e...
