在微晶叠层太阳能电池中实施减反射（AR）涂层是一个具有挑战性的过程，其中不仅更多的阳光应该被传导到电池中，而且子电池之间的电流匹配应该被保持或得到改善。本文采用杂化中空二氧化硅纳米球（HSN）溶胶在玻璃基片的单面或双面制备了新型双层增透膜。作为通过双层AR涂层改善光分布的结果，顶部和底部子电池之间的电流差降低到0.05 mA/cm 2，远小于未处理电池的电流差0.33 mA/cm 2。此外，生长在双面AR涂覆的基板上的细胞表现出顶部和底部亚细胞的电流密度的最大增加，分别为4.20%和7.53%，这远高于单面AR涂覆的基板上的细胞的电流密度。潜在的起源归因于更好的光捕获诱导的多尺度织构在前掺硼氧化锌（BZO）电极，这是由于从保形生长的BZO上的HSNs具有独特的表面形貌。研究结果提供了一种实用的方法，同时实现光分布和捕获使用双面AR涂层玻璃覆盖层，而无需任何修改的层内微晶叠层太阳能电池。
Implementing antireflection (AR) coatings in micromorph tandem solar cells is a challenging process in which not only more sunlight should get conducted into the cells, but also the current matching between subcells should either be maintained or get improved. In this work, the novel double-layered AR coatings were prepared on either one side or two sides of glass superstrates using hybridized hollow silica nanosphere (HSN) sols. As a result of improvement in light distribution via double-layered AR coatings, the current difference between the top and bottom subcells was decreased to be 0.05 mA/cm2, much smaller than that of untreated cells, 0.33 mA/cm2. Furthermore, the cells grown on the two-sided AR coated superstrates demonstrated the largest increases in current densities of top and bottom subcells, 4.20% and 7.53%, respectively, which were much higher than those of the cells on one-sided AR coated superstrates. The underlying origin was ascribed to the better light trapping induced by multiscale texturing at front boron-doped zinc oxide (BZO) electrodes, which resulted from the conformal growth of BZO on HSNs with unique surface morphologies. The findings provided a practical way to simultaneously realize light distribution and trapping using the two-sided AR coated glass superstrates without any amendment of layers inside micromorph tandem solar cells.
