Application: Solar cell, photovoltaic module, and electrical device (Patent ID: US20240213385A1)
The patent filed by Contemporary Amperex Technology Ltd. describes a solar cell with multiple sub-cells arranged sequentially along a direction perpendicular to their thickness. The thickness of the photovoltaic conversion layer in each sub-cell changes in a manner that is negatively correlated with the cross-sectional area of the layer, aiming to enhance the uniformity of photocurrents and electrical current output by the sub-cells. Additionally, the solar cell includes dead zones between adjacent sub-cells for electrical connections, with the thickness of the photovoltaic conversion layer in each sub-cell positively correlated with the cross-sectional area of the dead zones.
Furthermore, the solar cell design involves stepwise decreases in the thickness of the photovoltaic conversion layers and stepwise increases in the cross-sectional areas along the direction of arrangement. The dead zones also exhibit stepwise decreases in cross-sectional areas. The patent also includes details about the structure of the dead zones, comprising electrode layers, photovoltaic conversion layers, and run-through portions. The dimensions of certain portions within the dead zones decrease stepwise along the direction of arrangement. Overall, the patent aims to optimize the design of solar cells to improve the uniformity of photocurrents and electrical current output, enhancing the efficiency and performance of photovoltaic modules and electrical devices utilizing these solar cells.
