ELECTRODE

摘要

A photo voltaic cell comprising: a). a composite photo electrode, said composite photo electrode comprising a substrate supporting a porous photo active first charge carrier material, wherein the substrate consists of an electrically conductive network and the porous photo active first charge carrier material is located substantially within the network; b). a counter electrode; c). a second charge carrier material disposed such that a high surface area interface exists between the first and second charge carrier materials, and wherein the second charge carrier material is located between the counter electrode and the composite photo electrode; and d). a porous electrically insulating separator material, said separator material being disposed between the counter electrode and the second charge carrier material.
