The perovskite HJT laminated tile solar cell module comprises a plurality of cell piece modules, wherein each cell piece module comprises a back grid line, an HJT cell layer, a conductive substrate layer, an electron transport layer, a perovskite layer, a hole transport layer and a front grid electrode which are arranged in sequence, the top end of the HJT cell layer is a P side, the front grid electrode and the back grid electrode comprise at least two groups of main grids, and a plurality of auxiliary grids are arranged between the main grids; the main grids between the adjacent cell pieces are arranged in an overlapping manner and are connected through a conductive adhesive, and the surface main grid lines are connected through a low-temperature conductive adhesive tape, so that the aim of arranging more cell in a unit area is fulfilled; meanwhile, the voltage of the laminated cell is relatively high, so that the heat loss during transmission can be reduced; and the laminated cell assembly can be directly formed through coating-blowing crystallization, the preparation is rapid and convenient, the requirement for the HJT substrate is not high, the preparation can be conducted on the suede, and higher efficiency is obtained.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a perovskite HJT stacked shingled solar cell module and a preparation method thereof. Background technique [0002] In recent years, with the continuous deepening of research, perovskite cells have achieved rapid development, and the efficiency has increased from the initial 3.8% to 25.5%, known as "the new hope in the field of photovoltaics". HJT heterojunction cells have a short absorption spectrum (300-1200nm), but their low utilization rate for short-wave light absorption limits the efficiency, while perovskite has a high utilization rate for short-wave to visible light wavelengths (300-800nm). Superimposing perovskite cells on HJT cells can effectively increase the absorption range of different wavelengths of sunlight and obtain higher conversion efficiency. [0003] However, the use of traditional ribbon-connected cells involves local high temperature damage to perov...
