Novel entropy driven strategy for solar photons |
| 초록 |
The conversion and manipulation of light via lanthanide-based upconversion (UC) and downshifting (DS) show promise in numerous applications. We demonstrate the lanthanide-doped nanotemplates to improve conversion of ultraviolet and near-infrared to visible light through resonant-mode excitation. The templates are fabricated using nanoimprint technique wherein ordered arrays of nanoscale features are readily made over large areas. The practical applicability of this platform in photovoltaic devices is evaluated, showing distinctively enhanced efficiency. For further approach, we demonstrate the use of quaternary bulk heterojunctions composed of two conjugated polymer donors and two fullerene acceptors as a novel platform to produce high-efficiency and long-term durable organic photovoltaics. We attribute the enhanced stability to the significant suppression of domain growth and phase separation between the components via kinetic trapping effect. |
