A novel strategy was introduced to prepare Pt–SnO2 nanocomposite in one step. Pt–SnO2 nanocomposite counter electrode based dye-sensitized solar cells achieve an energy conversion efficiency of 8.83%, better than that for SnO2 CE and comparable with Pt CE based DSCs.

AbstractWe report dye-sensitized solar cells using low cost carbon nanoparticles as an alternative to platinum as a counter-electrode catalyst for triiodide reduction. The counter carbon-electrode was deposited onto fluorine-doped tin oxide (FTO) by spin coating from an aqueous colloidal suspension of the blend of carbon nanoparticles and TiO2 nanocrystals. DSSC devices were fabricated using a stable Ru complex dye (Z-907) as the sensitizer. The cells based on carbon-nanoparticle counter electrode were made and then compared with those cells from platinum counter electrode at similar fabrication conditions. The results have shown that the device performance in terms of short circuit current density (Jsc), open circuit voltage (Voc) and energy conversion efficiency (η) from the cells based on carbon nanoparticle counter electrode were comparable to those from platinum counter-electrode devices. The carbon nanoparticle based cells have achieved an overall energy conversion efficiency of 5.55% under one sun AM 1.5 illumination (100 mW/cm2). The carbon nanoparticles showed significant potential as a low cost alternative to the current widely-used platinum.

PtO–MWCNTs nanocomposites were prepared and applied as the counter electrode in dye-sensitized solar cells (DSCs) for the first time. Excellent energy conversion efficiency indicated that the nanocomposite was a promising electrocatalyst for DSCs.

An energy conversion efficiency of 8.31% is reached by using a cemented photoanode for dye-sensitized solar cells, attaining a 31.1% improvement over the standard Degussa P25 sample.
