  • Patent number: 9406821
    Abstract: Methods of fabricating back-contact solar cells and devices thereof are described. A method of fabricating a back-contact solar cell includes forming an N-type dopant source layer and a P-type dopant source layer above a material layer disposed above a substrate. The N-type dopant source layer is spaced apart from the P-type dopant source layer. The N-type dopant source layer and the P-type dopant source layer are heated. Subsequently, a trench is formed in the material layer, between the N-type and P-type dopant source layers.

  • Patent number: 7893409
    Abstract: A photoluminescence mapping system and method for use in fabricating solar cells that eliminates the need for complex and expensive light sources, filters and high sensitivity cameras. Generally, the method includes: (i) irradiating a surface of the substrate with radiation having a predetermined energy for a first predetermined period of time to photogenerate carriers therein; (ii) stopping the irradiation; (iii) exposing the surface of the substrate to a camera for a second predetermined period of time; and (iv) capturing with the camera a photoluminescence (PL) signal emitted from the surface of the substrate.

  • Publication number: 20100129955
    Abstract: A method for fabricating a solar cell is described. The method includes first providing, in a process chamber, a substrate having a light-receiving surface. An anti-reflective coating (ARC) layer is then formed, in the process chamber, above the light-receiving surface of the substrate. Finally, without removing the substrate from the process chamber, a protection layer is formed above the ARC layer.

  • Publication number: 20100071765
    Abstract: A method for fabricating a solar cell is described. The method includes first providing a substrate having a dielectric layer disposed thereon. A pin-hole-free masking layer is then formed above the dielectric layer. Finally, without the use of a mask, the pin-hole-free masking layer is patterned to form a patterned pin-hole-free masking layer.

  • Publication number: 20080314443
    Abstract: A solar cell is described. The solar cell is fabricated on a substrate, the substrate having a front surface and a back surface. The substrate includes, at the front surface, a first region having a first global thickness and a second region having a second global thickness.
