The dye sensitized solar cells (DSC) have been regarded as a promising candidate for next generation solar cells and attracted much attention owing to their low cost, low energy consumption, simple fabrication process and high power conversion efficiency. As a major component of the DSC, electrolyte has important impact on the performance and stability of DSC. In this paper, the operating principle of DSC and research progress of electrolyte, including liquid, solid state and quasi-solid-state electrolyte are described briefly. In addition, the application of low molecular mass organogelators (LMOG) in quasi-solid-state dye-sensitized solar cells is reviewed in details, and the application of LMOG in quasi-solid-state dye-sensitized solar cells is predicted.
