  • Solar cell having a dielectric rear face coating and method for producing same
    Patent number: 10115851
    Abstract: Solar cell (11; 21; 31) having a dielectric coating arranged on a back side of the solar cell (11; 21; 31) which is at least partly covered by at least one planar contact (12; 22; 32), a boundary line (14; 24; 34) of the at least one planar contact (12; 22; 32) having at least one recess (16a, 16b; 26a, 26b, 26c), and method for producing same.
    Type: Grant

  • METHOD FOR PRODUCING SILICON SOLOR CELLS HAVING A FRONT-SIDED TEXTURE AND A SMOOTH REAR SIDE
    Publication number: 20140051199
    Abstract: Method for producing a silicon solar cell which is smoothly etched on one side, in which a front side and a rear side of a silicon substrate are etched (10) to form a smooth texture, a dielectric coating is then formed (14, 16) on the rear side of the silicon substrate and the front side of the silicon substrate is subsequently textured (20) by means of a texture etching medium, the dielectric coating formed on the rear side of the silicon substrate being used as an etching mask against the texture etching medium.
