The constantly rising price of silicon feedstock has been the most important factor preventing photovoltaic (PV) energy from reaching grid parity. On the other hand, large amount of silicon gets wasted during slicing. We report a promising approach to recycle kerf loss silicon from cutting slurry waste for solar cell applications. Silicon …

The vast majority of reports are concerned with solving the problem of reduced light absorption in thin silicon solar cells 9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24, while very few works are ...
It was observed that the Nusselt number of MPCM slurry was much higher than for water as single-phase fluid, especially at higher mass fractions at the same flow rate. Moreover, the PV panel temperature was found to be significantly reduced when phase
1. Introduction The worldwide energy production of solar cells had increased to 2.6 GW in 2006 [1] and has been growing continuously in recent years, During monocrystalline silicon wafer manufacturing, 30 wt% of silicon goes into slurry waste due to kerf loss during this processing [2], [3], [4]..

To explore the feasibility and relative advantages of phase change slurry (PCS) as operating working medium, a solar hybrid vapor compression heat pump based on phase change slurry (PCS-PV/T-VCHP) is constructed by directly combining PCS as operating fluid ...
In this research, a study to selectively recover Si from end-of-life photovoltaic cells by using acid solutions (HNO3 and HCl) and the cavitation effect of an ultrasonic cleaner was ...
Microencapsulated phase change material (MPCM) slurry has proven to have potential in elevating the overall performance of a photovoltaic/thermal (PV/T) module as a working fluid. In order to make full use of the …

The weight percentage of CH weight loss to total weight loss is shown in Fig. 13. The CH content of the reference group was 17.11 %. With an increasing substitution rate, the addition of 30-min wet-grinding carbonated CSW decreased the CH content in the carbon-sequestered mortar by 8.70 %, 18.76 % and 34.60 %.
The dried slurry is found by the weight loss measurement to consist of 38.5 wt% Si and 61.5 wt% SiC. Fig. 2 gives a scanning electron micrograph of the dried slurry. With the help of EDAX probing analysis, it is identified that Si exists as tiny debris and SiC as chunks.
A new kind of PV/T collector with two different sorts of coolant fluids, water, and MPCM slurry, was presented by Liu et al. [40] in a 3D numerical study. By using MPCM slurry as a cooling fluid, the temperature of PV/T cells declines more significantly compared
Introduction The photovoltaic (PV) industry is going through a rapid growth. In 2006 alone, the global PV production was over 2 GW. The majority of PV cells are made of silicon, which is mainly produced from the energy-intensive Siemens process [1]. As per current ...
