Carbon Nitride and Conjugated Polymer Composite Materials
… function as an acceptor material improving the photocurrent generation both in solution and in solid state photovoltaic devices, with the external quantum efficiencies reaching 1% at high nitrogen contents. The occurrence of the donor–acceptor charge transfer was further evidenced by suppression …

Electrochemical and Photoelectrochemical Study of Conduction modes in Nanostructured TiO2 Films
… The results of EIS (Electrochemical Impedance Spectroscopy) mainly showed the presence of a barrier layer (junction metal/semiconductor or metal/oxide/semiconductor) between the TiO2 layer and the stainless steel in the absence and presence of niobium. The carrier density is estimated at almost …
