Origin of photovoltaic and photocurrent in the nanoporous dye-sensitized electrochemical solar cell
Article Abstract:
The charge separation and the photovoltaic functioning of the nanoporous dye-sensitized electrochemical solar cell was analyzed for the essential role of the dark equilibrium potential. A qualitative model was developed for the potential distribution in the sponge-type electrochemical solar cell. A unique screening process for the photogenerated electrons facilitated long lifetime because the screening ions could not function properly as recombination centered.

Photoelectric generation and second-order nonlinear optical characters of the dichromophore dye molecules
Article Abstract:
The use of the Langmuir-Blodgett (LB) technique enables centrosymmetric molecules to exhibit strong second-harmonic generation. Upon excitation of the dyes incorporated into LB films deposited on an ITO electrode, steady cathodic photocurrent was obtained. The observed quantum yield of the photocurrent strongly depends on the applied electrode potential, pH of the electrolyte, chemical structure of the dye congeners and the applied electrode potential.
