Abstract

The invention discloses a four-terminal perovskite and crystalline silicon laminated assembly. The assembly comprises a plurality of perovskite cells and a plurality of crystalline silicon cells positioned below the perovskite cells, wherein each perovskite battery is provided with a positive electrode I and a negative electrode I. The positive electrodes I and the negative electrodes I of the plurality of perovskite cells are connected in series to form a perovskite cell pack. Each crystalline silicon cells is provided with a positive electrode II and a negative electrode II, and the positiveelectrodes II and the negative electrodes II of the plurality of crystalline silicon cells are connected in series to form a crystalline silicon cell pack. The invention further discloses a preparation method of the four-terminal perovskite and crystalline silicon laminated assembly. According to the technical scheme, the purpose of improving the efficiency and stability of the laminated assemblyis achieved by adjusting the structure of the transparent conductive electrodes and the series connection mode of the laminated cells. The long-term reliability of the four-terminal laminated assembly adopting the independent series structure is improved to a certain extent under the condition of outdoor work.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a four-terminal perovskite and crystalline silicon stacked component and a preparation method. Background technique [0002] As the first generation of solar cells, crystalline silicon cells have undergone decades of technological innovation, and their mass production efficiency has been continuously improved. At present, the conversion efficiency of laboratory-scale crystalline silicon cells has reached 26.6%, which is constantly approaching its 29.4% conversion efficiency limit. In order to break through the photoelectric conversion efficiency, current researchers have turned their attention to stacked cells. Since the development of perovskite cells 10 years ago, their photoelectric conversion efficiency has rapidly increased from 3.8% to 25.2%. Inexpensive, efficient, and good tolerance to defects have become the notable labels of perovskites. As an organic-inorganic hy...
