摘要： A solar cell having a cell comprised of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs) with a back surface field (B S F) comprised of aluminum gallium arsenide (AlGaAs) or indium aluminum gallium arsenide (InAlGaAs) p-type doped for enhanced operation of the solar cell at temperatures less than −50° C. In one example, the back surface field comprises AlxGa1-xAs or In0.01AlxGa1-xAs, wherein x is less than about 0.8, for example, 0.2. The back surface field may be p-type doped with zinc (Zn) or carbon (C).

摘要： A solar cell for a solar cell array with one or more grid on a surface thereof, wherein electrical connections are made to the grids in a plurality of locations positioned around the solar cell; and the electrical connections extend to one or more conductors located under the solar cell. The conductors located under the solar cell are buried within a substrate, and each of the conductors comprises a low resistance conducting path that distributes current from the solar cell. The conductors are loops, U-shaped, or have only up or down pathways. The solar cell comprises a full cell that has four cropped corners and the locations are in the cropped corners.

摘要： Provided are methods and systems for treating shunts on solar cell substrates. Also provided are solar cells including such substrates. A shunt detected on a substrate proximate to a metallized grid pattern is electrically disconnected from at least the bus portion of the grid, which reduces shunt's impact on performance on the solar cell. An antireflective layer may be disposed between the shunt and a portion of the grid extending over the shunt. The exposure pattern of a photoresist used to form the antireflective layer may be adjusted accordingly to achieve this result. In some embodiments, the metallized grid may be modified by adjusting the exposure pattern of a photoresist used to form this grid. The grid may be modified to avoid any contact between the grid and the shunt or to disconnect a portion of the grid contacting the shunt from the bus portion area of the grid.

摘要： The present disclosure generally relates to broadband antireflective coatings for reducing reflection of light in the infrared without compromising visible light reflectance in multijunction solar cells bonded to coverglass, and methods of forming the same. The antireflective coatings include a high index, one or more intermediate index, and low index of refraction dielectric layers. The high index dielectric layer utilizes an ion beam assisted deposition to maximize the density and index of refraction. The intermediate index layer(s) increase the bandwidth of the antireflection coating, thereby improving the performance of the antireflective coating in the infrared spectrum.
