研究目的
Investigating the effect of energy band misalignment and morphology in In2O3-CNTs on electron transport in dye-sensitized solar cells to understand performance degradation and identify the optimum concentration of MWCNTs in In2O3 for DSSC.
研究成果
The study concludes that In2O3-MWCNTs (0.4 wt.%) exhibits the highest power conversion efficiency among the tested samples due to optimal MWCNTs concentration, leading to lower electron recombination rate and faster electron lifetime. However, the overall efficiency is still low, attributed to poor dye adsorption and electron transport issues caused by particle agglomeration and MWCNTs aggregation. The study suggests 0.4 wt.% as the optimum MWCNTs concentration in In2O3 for DSSC and recommends exploring hydrothermal route for improved morphology.
研究不足
The study highlights the technical constraints related to the CBD method leading to non-uniform and agglomerated In2O3 particles, which may affect dye adsorption and electron transport. The application is limited by the low power conversion efficiency achieved, suggesting the need for alternative preparation methods like hydrothermal route for morphology enhancement.
