Problems solved by technology

[0005] Using CH 3 NH 3 PB 3 The efficiency of solar cells with perovskite as photosensitive material has reached more than 20%, and the conversion efficiency can be further improved by using nanostructure modification on the surface of the cell. However, due to its band gap of 1.55eV, the spectral absorption range is limited to 300- Between 800nm, the spectrum in the near-infrared region is not fully utilized

Abstract

The invention discloses an SPPs (Surface Plasma Polaritons) thin film heterojunction and perovskite laminated solar cell and a preparation method of the solar cell. The solar cell comprises an aluminum electrode, an SPPs thin film heterojunction solar cell, an ITO connection layer, a triangular grating perovskite cell and a metal grid line electrode from bottom to top. The preparation method of the solar cell comprises the following steps: 1, preparing the SPPs thin film heterojunction solar cell; 2, preparing the ITO connection layer on a front surface of the SPPs thin film heterojunction cell by a magnetron sputtering coating system; 3, preparing the triangular grating perovskite cell; and 4, preparing the metal grid line electrode by a silk-screen printing method. The prepared solar cell first utilizes a perovskite top cell to absorb short-wavelength sunlight, and then utilizes a thin film heterojunction bottom cell to absorb long-wavelength sunlight, so as to form a reasonable laminated thin film cell structure, the spectral absorption range of the thin film cell is effectively expanded, and the photoelectric conversion efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of novel stacked solar cells, and relates to a stacked solar cell based on the combination of SPPs thin film heterojunction and perovskite and a preparation method thereof. Background technique [0002] In the cost share of finished silicon-based solar cells, silicon materials account for nearly 40%, while the thickness of thin-film solar cells is less than 1 μm, which is less than 1 / 100 of the thickness of crystalline silicon solar cells, which greatly reduces manufacturing costs. However, the reduced thickness also reduces the efficiency of thin-film solar cells. Through the light management design, the structure of "electrically thin" and "optical thick" can be realized, thereby improving the photoelectric conversion efficiency of the battery. [0003] Among all light management designs, the use of light-trapping structures is the most effective way to improve the photoelectric conversion efficiency of c...
