ABSTRACT:
The invention relates to a low cost photovoltaic cell, using a minimum thickness layer of semiconductor compounds able to provide the photovoltaic effect and specifically in polycrystalline form. On a molybdenum sheet an auxiliary polycrystalline germanium layer is deposited in order to facilitate subsequent depositions. This is followed by an intermediate polycrystalline layer of gallium aluminum arsenide and an active layer of polycrystalline gallium arsenide. The presence of the intermediate layer with a wider forbidden band than that of the active layer compensates the effect on the efficiency of the limited thickness of the active layer.
