镀膜方单晶组件在并网光伏系统中的研究
|
摘要
镀膜方单晶组件采用方形单晶硅电池片,利用气相沉淀方式,在太阳能组件钢化玻璃外表面镀上一层减反射膜,可减少光线反射,增加入射光,即提高光电转换效率。将镀膜方单晶组件接入并网光伏系统中,研究其在不同辐照度、膜表面积灰程度、膜表面手指印、膜表面刮痕等条件下的实际发电性能,并通过模拟仿真验证实验的准确性。结果表明:镀膜方单晶组件具有更高的光电转换效率,且在低辐照条件下更加明显;灰尘对组件发电性能的影响与辐照强度的大小有关;膜表面的手指印、刮痕对组件发电性能影响不大,可消除客户的担忧。
A coated quad mono-crystal silicon module was comprised of quad mono-crystal silicon solar cells,in order to improve the photovoltaic conversion efficiency,and the outside of the glass was coated with a layer antireflection coating with the method of vapor deposition to reduce reflectivity and increase incidence rate.The modules was connected to a grid-connected photovoltaic system,and their actual generated performance in different conditions were researched,such as different irradiation,the degree of accumulation of dust on the surface of the glass,fingerprints and scratches on the surface of the coating.The results show that the coated quad mono-crystal silicon module has higher photovoltaic conversion efficiency,and it is more obvious in low-irradiation conditions;the dust accumulation may affect the power generation of the modules significantly because of different irradiation conditions;the influence of fingerprints and scratches on the power generation of the modules is little,which can eliminate the concerns from customers.
