The influence of bilateral environment of dyed-TiO2/electrolyte interface on detailed recombination process during the a??maturea?? period of sensitized solar cell

摘要： The complete dye-sensitized solar cell (DSC) life cycle includes three stages: “mature” period, stability period and degradation period. However, during the DSC performance adjustment period, considering the in?uence of both sides of the dyed-TiO2/electrolyte interface on the electron recombination process is still blank. In this paper, the effects of the environment on both sides of the interface between TiO2 and electrolyte during the DSC performance adjustment on the electron recombination process are studied. The results show that the performance adjustment of DSC is greatly in?uenced by the chemical environment of electrolyte. The ?lm microstructures have a certain in?uence on the electron recombination process during the performance adjustment. During the performance adjustment period of DSC, the adjustment of quasi-Fermi level is more complicated under the condition of weak light than under the condition of strong light. The results of this paper are signi?cant for studying complex systems of DSC, understanding the device working mechanism and improving the cell ef?ciency.
