Smart Energy's Photovoltaic-Solar Integrated Solution

At present, solar photovoltaic generation is relatively inefficient, and most solar energy is not utilized.Under standard conditions, the conversion efficiency of solar crystalline silicon cell is about 12% ~ 16%, that is, about 80% of the solar energy irradiated to the surface of the cell will be converted into heat energy, which will cause the temperature of the cell to rise and the photoelectric conversion efficiency of the cell to decline.In summer, the temperature of photovoltaic panels without cooling measures usually reaches 70℃ ~ 80℃.For silicon cells, the photoelectric conversion efficiency decreases by 3‰ ~ 5‰ for every 1℃ increase in operating temperature.Integration of solar Photovoltaic solar-thermal Photovoltaic/Thermal and PV/T) systems use of solar energy Photovoltaic power generation at the same time provide living hot water/heating heat energy construction, to improve solar energy utilization efficiency, reduce the comprehensive cost of the system as a whole and reducing installation area has obvious advantages and application prospects.

In addition, the recycling of waste silicon solar cells is an important field in electronic waste treatment, especially the extraction of precious metal in solar cells. It is of great significance to adopt effective measurement methods to measure silver ions in waste silicon solar cells.Based on flame atomic absorption spectrometry (faas), the content of silver ions in crystalline silicon solar cells was determined
