HETERO-JUNCTION PHOTOVOLTAIC CELL

摘要

The invention provides photovoltaic cells of new design in which the two semiconductors have lattice parameters which differ by more than 5%. The n-type semiconductor material is constituted by high conductivity CdS doped with indium in a percentage higher than 1%, and the p-type semiconductor material is constituted by Si. The active surface of said cells is equal to or greater than 1.5 cm2.
