Description

Double-junction laminated solar cell and preparation method thereof
Technical Field
The invention relates to the field of solar cells, in particular to a novel double-junction laminated cell and a preparation method thereof.
Background
The crystalline silicon solar cell technology is the most mature photovoltaic power generation technology at present, and due to the advantages of the crystalline silicon solar cell technology in the aspects of comprehensive cost and conversion efficiency, other types of solar cells such as CIGS, OPV, gallium arsenide and other thin film cells are difficult to replace crystalline silicon cells in a short time, the performance of the crystalline silicon cells is continuously improved, and the technology is continuously optimized, so that the method has important significance in reducing the cost. However, the conventional crystalline silicon cell has some limitations in material and process, and the forbidden band width of crystalline silicon is 1.12eV and is an indirect band gap; in addition, the conventional crystalline silicon battery needs high temperature in the diffusion and sintering process, minority carrier recombination is aggravated in the high temperature processes, and the influence of auger recombination is more obvious in the thermal diffusion process, so that the open-circuit voltage limit value of the crystalline silicon battery is about 750mV, the theoretical limit efficiency of the crystalline silicon battery is about 29%, and the efficiency of the crystalline silicon battery is difficult to greatly improve. Therefore, a new heterojunction cell with upper and lower double absorption layers formed by materials with excellent optical and electrical properties and silicon is found, and the heterojunction cell has important significance for improving the spectral absorption rate and further improving the efficiency of the solar cell.
Antimony selenide sulfide Sb 2 (Se x S 1-x ) 3 The material is a V-VI family direct band gap semiconductor material with stable properties, and the earth crust is rich in content, safe and nontoxic. And has high light absorption coefficient, moderate band gap width and easy regulation (1.1-1.8eV), so the material is regarded as one of the most promising solar cell materials. The forbidden band widths of antimony selenide sulfide and crystalline silicon can be well complemented, the absorption spectrum of the solar cell is widened, and the double-junction laminated cell is very suitable for being manufactured; however, no research report about antimony selenide sulfide and a crystalline silicon tandem cell exists at present, and the research on the specific structure and the preparation method of the double-junction tandem cell is very little.
