Abstract

The invention discloses a two-dimensional carbon-based perovskite solar cell based on an aminoquinoline ionic liquid. The cell comprises a transparent conductive electrode, an electron transport layer, a mesoporous layer, and a perovskite light layer stacked sequentially from bottom to top. Absorber layer and counter electrode. The present invention uses hydrophobic ionic liquid 1-ethylamine hydroiodide quinoline bis-trifluoromethanesulfonimide salt ([ILNTF 2 ] + I ‑ ), CH 3 NH 3 I. Lead halide was used as raw material, and a new type of two-dimensional perovskite material was successfully prepared. 2 ] 2 (CH 3 NH 3 ) 9 Pb 10 X 31 Perovskite solar cells as light absorbing layers. In the invention, the perovskite solar cell system is prepared by combining the hydrophobic ionic liquid 1-ethylamine hydroiodide quinoline bistrifluoromethanesulfonimide salt with lead halide to form a perovskite structure into a perovskite solar cell system. The battery has the advantages of convenience, simplicity, economy, strong stability and high photoelectric conversion efficiency.

Description

Technical field

[0001] The present invention involves the field of solar cell preparation technology, especially a two -dimensional carbon -based perovskite solar cell based on amino pyrine -based ionic liquid. Background technique

[0002] Metal halide perovskite solar cells have direct gaps, high consolidation coefficients, high carrier migration rates, small excitement binding capacity, long load diffusion length and many other advantages. Rapid development, in just 10 years, battery efficiency increased from 3.8 % to 24.2 %. With the continuous improvement of battery efficiency, the stability and production cost of perovskite solar cells have become more and more concerned about researchers. However, the use of expensive metal electrodes as the electrode is not only high in cost, but also requires high -energy -consuming processes such as vacuum steaming plating to prepare. At the same time, it also needs expensive cave transmission materials. Therefore It has important pract...
