Degradation of GaAs Solar Cells
Papež, Nikola ; Pinčík,, Emil (oponent) ; Lazar, Josef (oponent) ; Sobola, Dinara (vedoucí práce)
Gallium arsenide based solar cells are among the most powerful types of solar cells available. Their main advantage is excellent resistance to thermal and ionising radiation, and therefore they are used primarily in demanding conditions. This dissertation describes the state of GaAs photovoltaic cells exposed to thermal stress, high cooling, gamma radiation and broad-spectrum laser irradiation. The samples were examined before, after and during these processes using several analytical and characterisation methods. The measurements were focused on the characterisation of the surface, optical and electrical properties. Limits and new behaviour of this type of photovoltaic cells have been discovered, which are also affected by thin protective and anti-reflective layers.
