The charge carrier mobility can vary considerably in organic semiconductors and metal oxides depending upon the charge carrier density and local morphology. Although the charge carrier density, and hence mobility, in operating solar cells varies significantly during a single current-voltage scan, there is no present means to accurately determine this mobility over such an operating regime. We previously reported a new measurement technique termed “Transient Optoelectronic Mobility extraction via Absorption Spectroscopy” (TMS) which does precisely this, enabling us to identify the effective charge density dependence of commonly employed organic hole-conductors and porous TiO2 in both solid-state dye-sensitized solar cell. Herein, I will present the application of TMA to an efficient solid-state hybrid solar cell using a novel D-A type conducting polymer as a hole tranporting material. |
