摘要
基于锡铅混合包晶石吸收体的窄带隙（NBG）包晶石太阳能电池存在严重的开路电压（V OC）损耗，这主要是由于器件界面的高缺陷密度和电荷载流子重组造成的。本研究探讨了 NBG 包晶单结电池（E g = 1.21 eV）的 V OC 损耗。优化后的 NBG 子电池被用于制造高效的全过氧化物串联太阳能电池 (TSC)。通过在聚(3,4-亚乙二氧基噻吩)聚(苯乙烯磺酸)（PEDOT:PSS）为基础的空穴传输层（HTL）和 NBG 过氧化物之间添加一层薄的聚(三芳基胺)夹层，实现了 V OC 的改善。最佳双层 HTL 使冠军功率转换效率 (PCE) 达到 20.3%，而基于 PEDOT:PSS 的控制器件的转换效率仅为 17.8%。单结 NBG 电池的 V OC 改进也成功地转移到了全过氧化物 TSC 上，从而实现了 2.00 V 的高 V OC 和 25.1% 的 PCE。
Overcoming the Open-Circuit Voltage Losses in Narrow Bandgap Perovskites for All-Perovskite Tandem Solar Cells.
Narrow-bandgap (NBG) perovskite solar cells based on tin-lead mixed perovskite absorbers suffer from significant open-circuit voltage (VOC) losses due primarily to a high defect density and charge carrier recombination at the device interfaces. In this study, the VOC losses in NBG perovskite single junction cells (Eg = 1.21 eV) are addressed. The optimized NBG subcell is then used to fabricate highly efficient all-perovskite tandem solar cells (TSCs). The improvement in the VOC is achieved via the addition of a thin poly(triarylamine) interlayer between the poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS)-based hole transport layer (HTL) and the NBG perovskite. The optimal bilayer HTL results in a champion power conversion efficiency (PCE) of 20.3%, compared to 17.8% of the PEDOT:PSS-based control device. The VOC improvement of the single-junction NBG cell is also successfully transferred to all-perovskite TSC, resulting in a high VOC of 2.00 V and a PCE of 25.1%.
