Methods for high-throughput validation of cell components for use in dye sensitized solar cells (DSCs) are needed as the global production of such cells becomes widespread. We have carried out preliminary investigations into the use of scanning electrochemical microscopy (SECM) for high-throughput screening of materials. By coupling the technique of SECM with a light source, we have examined the surface charge of non-earthed pseudo-DSCs under variable light conditions and screened substrates by varying the working electrode potential. By studying the surface currents in a series of tests in which one or more component of a DSC were varied, the effect of TiO2, dye and iodide/triiodide electrolyte on the surface characteristics have been examined. © 2013 Elsevier Ltd.
