Recent advances in dye-sensitized solar cells: from photoanodes, sensitizers and electrolytes to counter electrodes

Dye-sensitized solar cells (DSSCs), as low-cost photovoltaic devices compared to conventional silicon solar cells, have received widespread attention in recent years; although much work is required to reach optimal device efficiencies. This review highlights recent developments in DSSCs and their key components, including the photoanode, sensitizer, electrolyte and counter electrode.
