摘要
采用有限元分析软件对腐蚀前后太阳能电池单晶硅表面结构进行光学行为模拟分析,得到了单晶硅硅片腐蚀前后的表面电场、表面磁场、功率流和反射率的变化规律.研究表明,与腐蚀前相比,腐蚀后的单晶硅表面电场、磁场和功率流较大,当波长为700 nm时,腐蚀后单晶硅表面电场和磁场大约为腐蚀前的3倍和6倍;腐蚀后单晶硅表面功率流x分量分布均匀;反射率较低,具有较好的光学特性.
Abstract
;Finite element analysis software was used to simulate the optical behavior of the surface structure of monocrystalline silicon solar cells before and after corrosion,and the changing law of surface electric field,surface magnetic field,power flow,and reflectivity of monocrystalline silicon before and after corrosion was obtained.The re-sults show that the electric field,magnetic field and power flow on the surface of monocrystal silicon after corrosion are larger than those before corrosion.When the wavelength is 700nm,the electric field and magnetic field on the surface of monocrystal silicon after corrosion are about 3 times and 6 times than those before corrosion.After corro-sion,the x component of the power flow on the surface of monocrystalline silicon is evenly distributed.The reflec-tance is low,and it has better optical properties.
