Method for manufacturing a solar cell with passivation layers
A recently granted patent (Publication Number: US12002899B2) outlines a method for manufacturing solar cells. The process involves providing a wafer with a substrate and a doped conducting layer, where the substrate includes textured surfaces. A passivating contact layer is formed on one surface of the substrate, while a first passivation layer is applied to the doped conducting layer. A second passivation layer is then added to complete the solar cell matrix. The method also includes laser cutting the matrix to create individual solar cells, as well as forming electrodes on the passivation layers for electrical connection.
The patent further details the steps involved in preparing the wafer, including texturing treatment, diffusion of dopant elements, and etching to expose specific regions of the substrate. The process also covers the formation of the passivating contact layer through sequential layering of materials and subsequent etching steps. Additionally, the method describes the cutting of the wafer to create the substrate and the application of electrodes on the passivation layers for electrical connectivity. Overall, the patented method offers a comprehensive approach to manufacturing solar cells with specific surface textures and passivation layers to enhance efficiency and performance.
