[0002] Photovoltaic cells are widely used in our daily life, especially solar cells. There are many technologies for solar cells, and how to improve the photoelectric conversion efficiency is an important topic.

[0003] As shown in Figures 1 and 2, traditional solar cells are opaque in order to maximize the area of ​​the light-receiving layer and improve the photoelectric conversion efficiency. However, the photovoltaic cells installed on the display screen 100 need to be made into a grid shape because the content of the display screen below the photovoltaic cells needs to be visible. Therefore, the photovoltaic cells need to be made into a grid shape so that the light of the display screen 100 can pass through the grid, and at the same time, the grid area receives light energy and converts it into electrical energy. As shown, a diamond-shaped light-receiving grid is distributed on the functional layer 200 of the existing photovoltaic cell 2S. This regular light-receiving grid can easily cause interference between the RGB dot matrix of the display screen and the wiring of the photovoltaic cell 2S, thereby generating moiré fringes, which affects the photoelectric conversion efficiency of the photovoltaic cell.

[0029] As described in the background technology, the prior art is for photocells, which are widely used in our daily lives, especially solar cells. There are many technologies for solar cells, and how to improve the photoelectric conversion efficiency is an important topic. Traditional solar cells are opaque, and the purpose is to maximize the area of ​​the light-receiving layer to improve the photoelectric conversion efficiency. However, since the photocells installed on the display screen need to see the content of the display screen below the photocells, it is necessary to make the photocells into a grid shape, so that the light of the display screen can pass through the grid, and at the same time, the grid area receives light energy and converts it into electrical energy. As shown in Figures 1 and 2, diamond-shaped light-receiving grids are distributed on the functional layer 200 of the existing photocell. This regular light-receiving grid can easily cause interference between the RGB dot matrix of the display screen and the wiring of the photocell, and produce moiré fringes, which affects the photoelectric conversion efficiency of the photocell.
