For application of PEDOT:PSS, one of the issue to solve is the acidic property. It induces interfacial protonation and degrades the quality of the thin film, which results in low charge conductivity, reduced perovskite crystallinity, and poor device stability. Here, carbon quantum dots with silver dopant (Ag-CQD) are prepared to improve this issue. This newly designed Ag-CQD is facilely obtained via one step hydrothermal synthesis. It is added to the hole transport material (HTM), which leads to enhanced charge extraction and increased electrical conductivity. Moreover, it derives the effect of performance development on perovskite photovoltaics. As a factor of these results, it is proved that improved perovskite crystallinity, high efficiency hole extraction and electrical characteristics are enhanced by integrating Ag-CQD in PEDOT:PSS. This work provides an efficient route to realize more stable PSCs capable of delivering outstanding charge dynamics. |
