    摘要: An improved tandem solar cell includes a gallium arsenide phosphide top solar cell and silicon bottom solar cell. The gallium arsenide phosphide solar cell is fabricated on a transparent gallium phosphide substrate and either placed in series with the silicon solar cell for a two terminal device or wired separately for a four terminal device. The top solar cell should have an energy gap between 1.77 and 2.09 eV for optimum energy conversion efficiency. A compositionally graded transition layer between the gallium phosphide substrate and the active semiconductor layers reduces dislocations in the active region. A gallium phosphide cap layer over the gallium arsenide phosphide solar cell reduces surface recombination losses.

    摘要: Electrical path failures in thin film photovoltaic cells are avoided by disposing at least one blocking layer in the cell to prevent undesired electrical contact which might otherwise occur between the transparent and opaque electrical contacts as well as between one of the contacts and the semiconductor which is remote from it.
