Battery series connection method and perovskite battery

The invention provides a cell series connection method and a perovskite cell, and relates to the technical field of perovskite solar cells. And the top electrode enters the P2 groove through physical pressing of the pressing part, so that a series access is formed between the perovskite sub-cells, and series connection between the perovskite sub-cells is completed. According to the technical scheme, the pressing part applies physical pressure to the P2 groove, and the top electrode can form good contact in the P2 groove, so that the sub-cells are in good contact, the series resistance of the device is reduced, the photoelectric conversion efficiency is improved, the edge breakage effect on the edge of the laser scribing groove can be effectively reduced, and the packaging yield of the assembly is improved. 本申请提供了一种电池串联的方法和钙钛矿电池，涉及钙钛矿太阳能电池技术领域。通过下压部件物理给压，让顶电极进入P2沟槽，使得钙钛矿子电池之间形成串联通路，完成钙钛矿子电池之间的串联。下压部件对P2沟槽进行物理给压，能够让顶电极在P2沟槽中形成良好接触，从而使子电池之间接触良好，器件串联电阻减小，光电转换效率提升，还能有效减轻激光划线沟槽边缘出现崩边效应，提高组件封装良率。
