研究目的
Investigating the therapeutic effects of a specific herbal medicine on a particular disease.
研究成果
The study demonstrates that incorporating Mo1.33C MXene into PEDOT:PSS as a composite HTL significantly enhances the performance of polymer solar cells. The improved PCE is attributed to enhanced charge transport and extraction properties, as well as morphological improvements of the active layer. This approach paves the way for high-performance PSCs using inorganic 2D materials combined with PEDOT:PSS.
