Abstract

The invention relates to a mechanical laminated solar cell and a preparation method thereof. The mechanical laminated solar cell is a mechanical laminated solar cell composed of a top-layer transparent perovskite solar cell and a bottom-layer heterojunction quantum dot solar cell; the top-layer transparent perovskite solar cell comprises a transparent counter electrode, a hole transport layer, a perovskite light absorption layer, a titanium dioxide electron transport layer and FTO transparent conductive glass which are distributed from top to bottom sequentially; and the bottom-layer heterojunction quantum dot solar cell includes FTO transparent conductive glass, a TiO2 light anode, a p-n quantum dot heterojunction and a Ag counter electrode which are distributed from top to bottom sequentially. The invention also provides a preparation method of the mechanical laminated solar cell. According to the whole preparation process of the mechanical laminated solar cell, an all-solution method is adopted, and therefore, the preparation method has the advantages of simple preparation process, low energy consumption, low cost and the like, and can effectively improve the photoelectric conversion efficiency of the perovskite solar cell and make it have more potential for market application.

Description

technical field [0001] The invention relates to the technical field of solar cells and their preparation, in particular to a mechanical stack solar cell of a transparent perovskite cell and a heterojunction quantum dot cell and a preparation method thereof. Background technique [0002] New organic / inorganic hybrid perovskite solar cells have become a research hotspot in the field of new energy devices due to their high efficiency, low cost, simple process, and environmental friendliness. In 2006, Professor Miyasaka and others first proposed the perovskite-type inorganic / organic hybrid material organolead halide (ABX 3 : A = CH 3 NH 3 , B=Pb, X=Cl, I, Br) perovskite solar cells as light-absorbing materials. Since then, inorganic / organic hybrid perovskite materials have rapidly been widely and intensively studied in the field of optoelectronics. The conversion efficiency of perovskite solar cells has exceeded 22% in just 6 years, becoming the most meaningful breakthrough ...
