Carbon Nanotube/π-Conjugated Polymer Composites as a High Mobility Hole Collection Layer for Perovskite Solar Cells. |
| 초록 |
Carbon Nanotube/Conjugated Polymer Composites have gained popularity as a route toward the incorporation of carbon nanotubes into photovoltaics. In this work, a high efficiency perovskite solar cell with polymer HTM wrapped SWNTs was demonstrated. PTB7 and PTB7Th-wrapped SWNTs act as highly effective p-type charge transporters in perovskite solar cells. The red shift of UV-vis absorption spectra of p-conjugated polymers is due to the increased result of π-π stacking in the polymer-wrapped SWNTs. And the result has an impact that the hole-extraction is facilitated by the upshifting of the nanotube ionization potential due to its hole-doping by the surrounding polymer sheath. The hole transport and hole extraction in a conjugated polymer-wrapped carbon nanotube was increased from TR-PL experiments and electrical measurements. The PCE of 16.42% for nano-hybrid photovoltaic device is the highest efficiency reported for PrSCs devices employing any type of carbon nanotubes to date. |
