Semiconducting single‐walled carbon nanotubes (s‐SWNTs) are used as a protective interlayer between the lead sulfide colloidal quantum dot (PbS CQD) active layer and the anode of the solar cells (SCs). The introduction of the carbon nanotubes leads to increased device stability, with 85% of the initial performance retained after 100 h exposure to simulated solar light in ambient condition. This is in sharp contrast with the behavior of the device without s‐SWNTs, for which the photoconversion efficiency, the open circuit voltage, the short‐circuit current, and the fill factor all experiencing a sharp decrease. Therefore, the inclusion of s‐SWNT as interlayer in CQD SCs, give rise to SCs of identical efficiency (above 8.5%) and prevents their performance degradation.

顶部阳极下方的半导体单壁碳纳米管中间层增强量子点太阳能电池的稳定性

半导体单壁碳纳米管（s-SWNT）用作硫化铅胶体量子点（PbS CQD）活性层和太阳能电池（SCs）阳极之间的保护性中间层。碳纳米管的引入提高了设备​​的稳定性，在环境条件下暴露于模拟太阳光100小时后，其初始性能的85％得以保留。这与没有s‐SWNT的设备的行为形成鲜明对比，因为该设备的光转换效率，开路电压，短路电流和填充因子都急剧下降。因此，在CQD SC中将s-SWNT作为中间层包含在内，可以产生具有相同效率（高于8.5％）的SC，并防止其性能下降。
