摘要

对光伏电池和硅太阳能电池透明衬底的抗反射梯度涂层进行了计算机模拟。模拟结果表明,在玻璃表面沉积多孔膜和梯度多孔膜可使硅太阳电池的相对效率提高8.0%。考虑了降水对玻璃增透效果的影响。结果表明,在整个孔隙体积中填充水并不影响增透效果:太阳能电池的相对效率提高了6.8%。如果我们假设孔隙完全被煤烟填充,那么太阳能电池的相对效率将下降50%。基于MgF2-CaF2混合物的梯度增透涂层具有实际意义,因为它可以使太阳能电池的相对效率提高6.2%。仿真结果表明,在硅太阳能电池表面沉积基于SiO2-Si混合物的梯度增透涂层,可将短路电流密度提高到40.0 mA/cm2。

Modeling of Antireflective Gradient Coatings for Solar Cells

Modeling of Antireflective Gradient Coatings for Solar Cells

A computer simulation of antireflective gradient coatings for a transparent substrate of a photovoltaic battery and a silicon solar cell has been performed. The simulation results have shown that porous and gradient porous films deposited on glass increase the relative efficiency of a silicon solar cell by 8.0%. The influence of precipitation on the antireflection effect of glass is considered. It has been shown that filling the entire pore volume with water does not influence the antireflection effect: the relative efficiency of the solar cell increases by 6.8%. If we assume that the pores are completely filled with soot, then the relative efficiency of the solar cell will decrease by 50%. A gradient antireflection coating based on a mixture of MgF2–CaF2 is of practical interest since it may increase the relative efficiency of the solar cell by 6.2%. The simulation has established that the short-circuit current density can be increased to 40.0 mA/cm2 if a gradient antireflective coating based on a SiO2–Si mixture is deposited on the surface of a silicon solar cell.
