The preparation of room temperature phosphorescent carbon dots still faces great challenges, especially in the case endowed visible-light excitable phosphorescence (RTP). To date, a limited number substrates have been exploited to synthesize dots, and most them can emit RTP only solid state. Here, synthesis composite obtained from calcination green (g-CDs) blended with aluminum hydroxide (Al(OH)3 ) is reported. resultant hybrid material g-CDs@Al2 O3 exhibits blue fluorescence emissions an...
Graphene quantum dots (GQDs) have wide prospective applications for optoelectronic fields owing to their unique characteristics, such as tunable bandgaps, high chemical and optical stability, well good biocompatibility. In this work, we offered a convenient proposal obtain uniform blue-green emissive GQDs modified efficient orange-emitting graphene (D-GQDs) derived from fullerene (C60) under acid-free conditions. The as-prepared D-GQDs demonstrate remarkable conversion efficiency, which the...
In contrast to conventional nanomaterials or organic dyes, carbon dots possess a variety of appealing properties including chemical inertness and easy manipulation they can be dispersed in water.
Solar grade silicon (SoG-Si) is the key material for photovoltaic applications. In this study, grain size, concentration of HF, leaching time and temperature were investigated by orthogonal methods. The results showed that size most important factor purification silicon. Furthermore, obvious removal efficiency iron aluminum was observed when mannitol used as chelated reagent in HF process. Inductive coupled plasma atomic emission spectroscopy (ICP-AES) indicated purity samples improved to a...
Refining of solar grade silicon by metallurgical method is the research hotspot polycrystalline field. Slagging benefit to removal impurities especially boron exsisted in raw silicon. In this study, influence density, viscosity and liquidus temperature slag components on refining process were discussed, then system SiO2-Na2CO3 was choosed as slagging agents. And impact factors efficiency such composition SiO2 Na2CO3, ratio time investigated orthogonal experiment. The results showed that...
The aim of this study is to evaluate the effect boric acid as an additive for gelled electrolytes. Cyclic voltammetry (CV), linear sweep (LSV), electrochemical impedance spectroscopy (EIS) and equivalent circuit analysis were employed performance electrolyte with addition varying amounts acid. Scanning electron microscope (SEM) was observe grid corrosion in test. For moderate contents acid, electrode capacity improved, well oxygen evolution profermance. However, adverse effects found include...
Ag nanoparticles arrays were fabricated by self-assembly method to accommodate manufacturing process of traditional silicon solar cells. Surface morphologies films (5-27.5 nm) after annealing treatment with 260 °C and 400 analyzed. The results showed that temperature has important impact on self-assembled arrays. tuning function SiN x dielectric film was also absorption peak generates a redshift the maximum range about 100 nm in spectrum, widths become wider increase thickness for same...
In recent years, photovoltaic industry has developed rapidly[1]. Facing the situation of traditional energy resources exhaustion and continuing oil price rise, solar as a renewable clean been focus world attention. all kinds battery, polysilicon cell is most important. However, high cost polysilicon, which accounts for 50% total cost, hinders development industry. this paper, purpose reducing production, metallurgy methods, example, chloridizing roasting applied purification. A feasible...
A low-cost process for removing boron from metallurgical grade silicon was developed by Si-Al alloying, and the separation procedure of grains melt solidification investigated in this paper. The microstructure purity were characterized detected metallographic analysis, energy dispersive X-ray spectrometers analysis inductive coupled plasma atomic emission spectroscopy analysis. results showed that content purified decreased 128.00 ppmw to 27.62 ppmw. In addition, purification with alloying...
