A V-grooved GaAs solar cell [PDF]

Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference, 1988
A GaAs homojunction cell was fabricated by etching a V-groove pattern into an n-epilayer (2.1*10/sup 17/ cm/sup -3/) grown by MOCVD (metal-organic chemical vapor deposition) on an n/sup +/ substrate (2.8*10/sup 18/ cm/sup -3/) and then depositing on MOCVD p-epilayer (4.2*10/sup 18/ cm/sup -3/).

GaAs concentrator solar cell

Applied Physics Letters, 1975
For terrestrial applications, the figure of merit for photovoltaic solar energy conversion devices is watts output per dollar of cost. AlGaAs/GaAs heterojunction cells have a very favorable watts per dollar figure of merit when used at high values of sunlight concentration. An experimental 1/2−in.−diam cell was operated in air mass 1.4 sunlight with an

Patterned Radial GaAs Nanopillar Solar Cells

Nano Letters, 2011
Photovoltaic devices using GaAs nanopillar radial p-n junctions are demonstrated by means of catalyst-free selective-area metal-organic chemical vapor deposition. Dense, large-area, lithographically defined vertical arrays of nanowires with uniform spacing and dimensions allow for power conversion efficiencies for this material system of 2.54% (AM 1.5 ...

Lightweight GaAs/Ge solar cells

Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference, 1988
For many space power applications it would be attractive to have a solar cell with the high conversion efficiency and radiation resistance characteristic of GaAs, but with a specific weight characteristic that can compete with silicon. Because of the fragility of GaAs substrates, practical GaAs/GaAs cells are limited to a thickness of about 8 mils.

Limiting efficiency of GaAs solar cells

Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference, 1988
The limiting efficiencies of GaAs solar cells when used under concentrated sunlight are calculated. An assessment of the benefits to be expected from applying techniques which restrict the angle of acceptance of the cell is made. It is concluded that by restricting the acceptance angle the emission of luminescent photons and the associated current loss
