  • Photovoltaic cell
    Patent number: 5240510
    Abstract: A solar cell having an active zone made of a polar polymeric film material is disclosed. The electric contacts on the surfaces of the active zone are made of metals differing in electrochemical potentials. At least one of the electric contacts has a coating that absorbs solar radiation. The absorbent coating is preferably applied to the electric contact in the form of a polymeric material whose shape approximates a hemisphere. The active zone surface and the electric contact surface free of hemispherical portions are provided with an absorbent coating made of a material whose absorbing capability is different from that of the material of the hemispherical portions.
