染料敏化太阳能电池（DSC）的整个生命周期包括三个阶段：“成熟”期、稳定期和退化期。然而，在DSC性能调整期间，考虑染料-TiO 2/电解质界面两侧对电子复合过程的影响仍然是空白。本文研究了DSC性能调整过程中TiO 2与电解质界面两侧环境对电子复合过程的影响。结果表明，电解液的化学环境对DSC的性能调节有很大影响。薄膜微结构对性能调整过程中的电子复合过程有一定的影响。在DSC的性能调整期间，弱光条件下准费米能级的调整要比强光条件下复杂得多。本文的研究结果对于研究DSC复杂体系、理解器件工作机理、提高电池效率具有重要意义。
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 influence 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 TiO2and electrolyte during the DSC performance adjustment on the electron recombination process are studied. The results show that the performance adjustment of DSC is greatly influenced by the chemical environment of electrolyte. The film microstructures have a certain influence 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 significant for studying complex systems of DSC, understanding the device working mechanism and improving the cell efficiency.
