抽象。已知多结太阳能电池中的发光耦合效应有助于通过载流子再分布实现子电池之间的电流匹配。我们使用防潮、全无机钙钛矿量子点（PQD）薄膜演示了III-V族多结太阳能电池器件中的载流子再分布。将该疏水PQD膜施加在全III-V多结太阳能电池器件上。这成功地证明了垂直的电流再分布，其通过较低带隙子电池中增加的电流收集来示出，并且横向的电流再分布，如从与发光起源的较高带隙子电池相邻的较低带隙子电池中改善的电流收集均匀性所观察到的。
Abstract. The luminescent coupling effect in a multijunction solar cell is known to help achieve current matching among subcells through carrier redistribution. We demonstrate the carrier redistribution in III-V multijunction solar cell devices using a moisture-resistant, all-inorganic perovskite quantum dot (PQD) film. This hydrophobic PQD film was applied on a full III-V multijunction solar cell device. This successfully demonstrated current redistribution vertically, shown by the increased current collection in the lower bandgap subcells, and laterally, as observed from improved current collection homogeneity in the lower bandgap subcell adjacent to the higher bandgap subcell where the luminescence originated.
