摘　　要：A new type quasi-solid state electrolyte was prepared by solidifying liquid electrolytes con- taining organic solvents (such as mixture of ethylene carbonate (EC) and propylene carbonate (PC), 3- methoxypropinitrile (NMP) and N-methyl-oxazolidin- one (NMO)) with comb-like molten salt type polymer, and was for the first time employed in dyesensitized solar cells (DSSCs). The optimal electrolyte compo- sition was obtained by regulating the polymer content in the electrolytes and optimizing performance data of the electrolytes and assembled cells, yielding a maximum conversion efficiency of 6.58% (AM 1.5, 100 mW·cm?2). Furthermore, the existence of this new type polymer in the electrolyte suppresses the evaporation of organic solvent and improves the sta- bility of the cells.A new type quasi-solid state electrolyte was prepared by solidifying liquid electrolytes containing organic solvents （such as mixture of ethylene carbonate （EC） and propylene carbonate （PC）, 3- methoxypropinitrile （NMP） and N-methyl-oxazolidinone （NMO）） with comb-like molten salt type polymer, and was for the first time employed in dyesensitized solar cells （DSSCs）.
