Show Abstract
The electrochemical polymerization of pyrrole on a polymer‐coated electrode produces an electrically conducting polymer‐polypyrrole alloy film. The surface resistance and the optical transmission of the alloy film can be controlled by the polymerization conditions, and semitransparent conducting films with a transmittance of 60% and a conductivity of 2/Ω cm can be realized.

Show Abstract
Preliminary results are presented of the photoacoustic phase angle dependence, for a Si solar cell, on load resistance, illumination intensity, and photon energy. The data are interpreted using a simple, phenomenological model that assigns the thermal loss mechanisms occurring in the photovoltaic device to the diffused (top) layer, the junction region, and the base of the cell.
