Abstract

The invention belongs to the technical field of perovskite solar cells, and particularly relates to an inorganic perovskite solar cell without a hole transport layer and a preparation method thereof.The solar cell is sequentially provided with conductive glass, a luminous layer, an electron transport layer and a metal electrode in a laminated mode. The luminescent layer is a Sn-Pb alloy perovskite thin film with a molecular formula of CsSn 1-x Pb x I 3, wherein x is larger than 0 and is less than 1. The preparation of the solar cell without the hole transport layer is realized by using the CsSn 1-x Pb x I 3 perovskite material as a luminescent layer, so that the structure of the solar cell is further simplified, and the cost is reduced. In addition, the HTM-free solar cell based on CsSn 1-x Pb x I 3 has stable photoelectric conversion efficiency and no obvious hysteresis.

Description

technical field [0001] The invention belongs to the technical field of perovskite solar cells, and in particular relates to an inorganic perovskite solar cell without a hole transport layer and a preparation method thereof. Background technique [0002] In recent years, organic-inorganic hybrid halide perovskite materials have become popular in the field due to their unique physical and chemical properties, such as high optical absorption, high carrier mobility, long diffusion length, and low cost and solvent processability. Optoelectronic devices such as solar cells have received extensive attention. Although this high-performance perovskite solar cell has been improved through continuous research and is beginning to be comparable to commercial silicon-based solar cells, the long-term stability of perovskite remains a problem as companies begin to commercialize it on a large scale. Perovskite solar cells with better performance usually contain organic cations such as methy...
