Huawei published a patent for Solar Cells

Huawei published a patent for “Solar Cells and their Preparation Methods, Smart Glasses, and Electronic Equipment”, the publication number is CN113421977A, and the application date is in May 2021.

According to the information, the application provides a solar cell and its preparation method, smart glasses and electronic equipment, which can reduce the influence of the thin film resistance on the cell efficiency after the cell size is enlarged, and adapt to the development trend of large-area solar cell applications.

The solar cell includes a first conductive layer, a second conductive layer, a first conductive grid, a second conductive grid, and a functional layer. The first conductive layer and the second conductive layer are laminated, and the functional layer is arranged between the first conductive layer and the second conductive layer.

One side of the first conductive grid is in contact with the side of the first conductive layer away from the functional layer, and the first conductive grid is used to output photocurrent to the target device;

The second conductive grid is embedded in the functional layer, and one side of the second conductive grid is in contact with the second conductive layer, and the second conductive grid is used for outputting photocurrent to the target device.
