多结太阳能电池为超越单结器件的Shockley-Queisser极限提供了一条途径。在短短几年内，硅-钙钛矿串联电池的效率已经大大超过了最好的硅单结电池。对于硅-钙钛矿串联器件的可扩展溶液处理，避免了真空处理步骤，通常需要一个扁平的硅子电池。这导致了一个平坦的顶部表面，可以导致更高的光学反射损失比共形沉积在有纹理的硅底部电池。为了克服这个问题，可以在成品电池的顶部使用纹理抗反射涂层（arc），其中纹理聚二甲基硅氧烷（PDMS）是一种很有前途的候选材料。在这项工作中，我们改变了PDMS减反射箔的纹理几何形状和膜厚度，以了解这些参数对膜反射率的影响。选择了最佳薄膜，并与两种常见的平面电弧——氟化锂（LiF）和氟化镁（MgF2）的抗反射性能进行了比较，结果表明，无纹理硅-钙钛矿串联电池的反射率明显降低。PDMS薄膜的应用表明，在硅-钙钛矿串联结构的每个子电池中，集成JSC增加了3-5%。
Multijunction solar cells offer a route to exceed the Shockley–Queisser limit for single-junction devices. In a few short years, silicon-perovskite tandems have significantly passed the efficiency of the best silicon single-junction cells. For scalable solution processing of silicon-perovskite tandem devices, with the avoidance of vacuum processing steps, a flat silicon sub-cell is normally required. This results in a flat top surface that can lead to higher optical reflection losses than conformal deposition on textured silicon bottom cells. To overcome this, textured anti-reflective coatings (ARCs) can be used on top of the finished cell, with textured polydimethylsiloxane (PDMS), a promising candidate. In this work, we vary the texture geometry and film thickness of PDMS anti-reflective foils to understand the effect of these parameters on reflectance of the foil. The best film is selected, and anti-reflective performance is compared with two common planar ARCs—lithium fluoride (LiF) and magnesium fluoride (MgF2) showing considerable reduction in reflectance for a non-textured silicon-perovskite tandem cell. The application of a PDMS film is shown to give a 3–5% increase in integrated JSC in each sub-cell of a silicon-perovskite tandem structure.
