Advances in Liquid‐Electrolyte and Solid‐State Dye‐Sensitized Solar Cells

Abstract

Abstract 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‐TiO 2 mesoporous metal‐oxide electrodes employed in dye‐sensitized solar cells.
