Experimental study on photovoltaic/thermal system performance based on microencapsulated phase change material slurry …
ABSTRACT Microencapsulated phase change material slurry (MPCMS) as working fluid has a certain potential to enhance the PV/T system capability. An experimental study was carried out to explore the impacts of water flux (0–0.0085 kg/s) and MPCMS mass concentration (0–5%) on electrical properties and thermal properties of the PV/T system …

Review on Metallization Approaches for High-Efficiency Silicon Heterojunction Solar Cells …
Screen Printing Technology Screen printing is the most widely used contact formation technique for industrial c-Si solar cells due to its high productivity, high reliability, easy handling, and cost efficiency. The evolution of the linewidth (finger width, W f) over the last 15 years obtained with screen printing in the PV industry is shown in Fig. 2a [].
A novel approach for recycling of kerf loss silicon from cutting slurry waste for solar cell …
The majority of PV cells are made of silicon, which is mainly produced from the energy-intensive Siemens process [1]. As per current status, the wafer shares more than 65% of the cost for solar cells, but on the other hand, more than 40% of the high-purity silicon is wasted during wafer slicing.
Recovery of solar grade silicon from kerf loss slurry waste
It can be considered as a new source of production of low-cost solar-grade polysilicon feedstock material with the potential to recover enough polysilicon to generate over 300 MW/year of crystalline silicon solar cells, i.e., more than two times the size of the
Uniform cooling for concentrator photovoltaic cell by micro-encapsulated phase change material slurry …
The concentrator photovoltaic (CPV) systems often suffer high heat flux, leading to cell temperatures rising, which will affect its performance and reduce the service life. Double-layered minichannel heat sink (DL-MCHS) is an efficient cooling technology, which could effectively lower down the top temperature of CPV cell.
