  • Method for forming selective emitter of solar cell and diffusion apparatus for forming the same
    Patent number: 8053343
    Abstract: A method for forming a selective emitter of a solar cell and a diffusion apparatus for forming the same are provided. The method includes texturing a surface of a silicon substrate by etching the silicon substrate, coating an impurity solution on the surface of the silicon substrate, injecting a first thermal energy into the whole surface of the silicon substrate, and, while the first thermal energy is injected into the whole surface of the silicon substrate, injecting a second thermal energy by irradiating a laser beam into a partial region of the surface of the silicon substrate.
