Abstract

Luminescent solar concentrators (LSCs) are attractive for the easy operation and high compatibility with building integrated photovoltaics due to their low cost, large-scale and applicability. However, underutilized sunlight in visible wavelengths often impedes the advance of LSCs. Here, we demonstrate an orange-emitting carbon nanodots-based LSC (O-CDs) with excitation concentrated in the visible wavelengths. The orange-emitting carbon nanodots (O-CDs) with highly localized excitonic emission are prepared via atomic condensation of doped pyrrolic nitrogen, delivering a high photoluminescence quantum yield of 80 % and a suitable Stokes shift with absorption spectrum situated in the visible region. The O-CDs are embedded in polyvinylpyrrolidone to obtain a highly transparent, stable and environmentally friendly O-CDs-based LSC. Thanks to efficient utilization of solar radiation in visible areas and well match between the emission of O-CDs and the response bands of photovoltaic cells, the O-CDs-based LSC reveals an optical conversion efficiency of 5.17 %, superior to that of most carbon nanodots-based LSCs. These results provide an effective strategy to develop carbon-based luminescent concentrated materials for architectural integrated photovoltaic technology.

Abstract

In order to study the cause of wire falling accident caused by fracture of 500 kV composite insulator in the no-fly zone of a province， various inspections and tests were carried out on the accident insulator string according to the current standard. The results of comprehensive detection and analysis and on-site fault investigation show that due to the defects in the interface between the glass fiber and the silicone rubber sheath of the composite insulator rod， the rod of the insulator is aged after many years of operation. In addition， due to the comprehensive influence of the operating environment， the internal fibrosis and overall structural degeneration of the rod are aggravated， which eventually causes the insulator to break down and cause the wire to fall off. Finally， in order to avoid the recurrence of such accidents and ensure the safe and stable operation of the power grid， the operation and maintenance strategy of composite insulators is given for the lines under the jurisdiction of the UAV no-fly zone and weak signal zone.
