  • H.J.S. thanks Clare College for funding via a Junior Research Fellowship. L.S.-M. acknowledges funding from the European Commission (Marie Curie Excellence Grant “NanoFen”, MEXT-CT-2004-014156) and thanks the Royal Society for a University Research Fellowship. The authors thank Prof. Michael Grätzel for introducing them to dye-sensitized solar cells and Dr. Bernard Wenger for valuable discussions.


This Progress Report highlights recent developments in dye-sensitized solar cells composed of both liquid electrolytes and solid-state hole transport materials. The authors discuss and review the present understanding of and recent developments in the operational processes, such as charge generation, transport, recombination, and charge collection. Also, the merits and challenges of alternative device approaches are discussed, including extremely thin absorber cells, devices containing inorganic p-type hole-transporters and non-TiO2 mesoporous metal-oxide electrodes employed in dye-sensitized solar cells.
