  • Patent number: 11024753
    Abstract: A PERC solar cell capable of improving photoelectric conversion efficiency and a preparation method thereof are provided. The solar cell consecutively includes, from the bottom up, a rear silver electrode (1), a rear aluminum field (2), a rear silicon nitride film (3), a rear aluminum oxide film (4), P-type silicon (5), N-type silicon (6), a front silicon nitride film (7), and a front silver electrode (8). The rear aluminum field (2) is connected to the P-type silicon (5) via a rear aluminum strip (10). The P-type silicon (5) is a silicon wafer of the cell. The N-type silicon (6) is an N-type emitter formed by diffusion via the front surface of the silicon wafer. The front silicon nitride film (7) is deposited on the front surface of the silicon wafer. The rear aluminum oxide film (4) is deposited on the rear surface of the silicon wafer.
