  • 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.

  • SOLAR CELL WITH DIELECTRIC BACK REFLECTIVE COATING
    Publication number: 20160133774
    Abstract: In a method for producing a solar cell, a layer stack of dielectric layers is applied to a back of a solar cell substrate and the layer stack is heated and is held at temperatures of at least 700° C. during a time period of at least 5 minutes. The novel solar cell has a layer stack of dielectric layers on its back. At least one of the dielectric layers of the layer stack is densified so that its resistivity to firing-through of pastes with glass components is enhanced.

  • 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.

  • METHOD FOR DOPING A SEMICONDUCTOR SUBSTRATE, AND SOLAR CELL HAVING TWO-STAGE DOPING
    Publication number: 20130014819
    Abstract: A method for doping a semiconductor substrate includes heating the semiconductor substrate by irradiation with laser radiation and at the same time diffusing dopant from a dopant source into the semiconductor substrate in heated regions. The semiconductor substrate is heated by the irradiation with laser radiation. A surface portion of the semiconductor substrate that is less than 10% of the total surface of all irradiated regions is melted and recrystallized. There is also provided a solar cell.

  • TUNNEL DIODES COMPRISING STRESS-COMPENSATED COMPOUND SEMICONDUCTOR LAYERS
    Publication number: 20120138130
    Abstract: The invention relates to semiconductor components, in particular solar cells made of III-V compound semiconductors, as are used in terrestrial PV concentrator systems or for electrical energy supply in satellites. However it is also used in other optoelectronic components, such as lasers and light diodes, where either high tunnel current densities are necessary or special materials are used and where stress in the entire structure is not desired.
