AbstractThe charge collection efficiency at organic semiconductor/transparent conducting oxide (TCO) interfaces is one of the key parameters controlling the overall efficiency of organic photovoltaics (OPVs). Using Cyclic Voltammetry (CV), the electrochemical surface coverage of an organic semiconductor molecule (a substituted perylene diimide, PDI) was evaluated in order to determine an optimal deposition procedure to obtain a monolayer of PDI on the indium-tin oxide (ITO) surface. The electron transfer rate constant of PDI molecules across the PDI/TTO interface was also evaluated using CV.
