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 solar system with the impure PCM situated at the back of the solar collector (shown in Figs. 29 and 30) was experimented and simulated by Biwole et al. using the CFD. The results presented that adding PCM to the back of the solar collector could maintain the operating temperature of the collector below 40 °C for 80 min with a constant solar radiation of 1000
