| Time：2013-5-2 Hit：3 |
Low reflection used in lighting glass solar photovoltaic system fouling self-cleaning technology: because the lighting glass solar photovoltaic panels on the long-term outdoor sunlight rain pro and pollution environment, like building glass, a period of time after the glass surface will form a layer of dirt, the dirt layer will affect the penetration rate light, thus greatly reduce the conversion efficiency of solar photovoltaic cells, even if it is a transparent glass, optical good glass, although the initial performance is very good, but not a piece of glass in the outdoor long-term use under the surface can keep clean, even if the silicon chip using the high efficiency and expensive, or cannot afford to glass outside pollution, therefore, the most effective solution to catch block is how to maintain the lighting glass surface cleanliness is a major breakthrough in key.
Solar energy is one of the most fiery energy at present, industry are mustering their efforts to develop new technologies and new products, hoping to improve the photoelectric conversion efficiency, even if only 1% of the increase, is in a very great. Lighting glass is an essential part of solar photovoltaic system, its daylight penetration rate is proportional to the photoelectric conversion efficiency, because the sunlight penetration rate decreased due to the surface of the glass by the pollution of the environment, even down to only 60%, so if not effectively solve the lighting glass surface pollution problems, will obliterate the industry to improve the photoelectric conversion efficiency efforts.
Because the lighting glass solar photovoltaic panels on the long-term outdoor sunlight rain pro and pollution environment, like building glass, a period of time after the glass surface will form a layer of dirt, the dirt layer will affect the penetration of light, it will greatly reduce the conversion efficiency of solar photovoltaic cells, the if it is a transparent glass, optical good glass, although the initial performance is very good, but not a piece of glass can be used for a long time under the surface can keep clean in the outdoors, even if the silicon chip using the high efficiency and expensive, or can not afford to glass outside pollution, therefore, to solutions effective is how to maintain the lighting glass surface cleanliness is a major breakthrough in key.
Nanometer material lighting glass surface fouling of solar photovoltaic cells, in a layer of protective layer formed lighting glass surface photovoltaic cells, the protective layer to keep the surface clean degree can be in a beam of sunlight and rain, the most important is the optical coating with nanometer material and lighting glass combination does not affect the glass the penetration rate, which is the most significant technical breakthroughs, because the market generally coating will result in decreased light penetration rate.
By the actual data when the super white glass surface oil pollution after the glass light penetration rate obviously dropped to only about 70%, but coated nano coating ultra-white glass can under the irradiation of light can gradually improve light penetration rate until such new glass is generally about 90% above, so to keep the solar photovoltaic battery conversion efficiency; but generally contaminated ultra-white glass under the irradiation of light is still maintained at a low light penetration rate, can not be the elimination of pollutants, is bound to make the conversion efficiency of solar cells decreased |
