Abstract

This application relates to a solar cell module and a method for preparing the same, a photovoltaic device, an electrical device, and a power generation device. In two adjacent sub-cells, a conductor is connected to a conductive layer of one sub-cell, with at least a portion protruding beyond at least one end of the conductive layer along a second direction. The electrode layer of the other sub-cell can connect with the protruding portion of the conductor outside the sub-cell, achieving series connection between the two sub-cells outside the sub-cells. This eliminates the need for the conventional two scribing operations before electrode layer deposition to achieve series connection, requiring only a cutting operation between sub-cells. Such a design, by providing a conductor protruding at least one end of the conductive layer along the second direction, eliminates the two scribing operations before sub-cell series connection, facilitating a single-cut preparation method, simplifying the preparation process, and improving preparation efficiency. Additionally, eliminating the two scribing operations reduces the likelihood of increased series resistance between sub-cells, thereby enhancing module performance.
