Abstract

Perovskite whentandemed with organic photovoltaics (OPV) for double-junctions have efficiencypotentials over 40%. However, there is still room for improvement suchas better current matching, higher fill factor, as well as lower voltage and fill factor losses in the top perovskite cell. Here weaddress the issue associated with the top perovskite cell by utilising anovel halogenated polycyclic aromatic hydrocarbon compound, 1-naphthylammoniumchloride (NA─Cl) playing dual roles of surface modification for the hole selectivelayer (HSL) and passivation of HSL/perovskiteinterface. Results of X-ray photoelectron spectroscopy and density functionaltheory calculations reveal that NA─Cl retains self-assembly property for the HSLwhile demonstrating high dipole moment and polarizability. This induces asurface dipole at the HSL/perovskite interface reducing the energetic barrierfor hole extraction by 210 meV thereby enhancing voltage output and fill factorof the device. Such scheme when implemented in a high bandgap (1.78 eV)perovskite solar cell, results in a respectable efficiency of 19.7% and thehighest fill factor of 85.4% amongst those of 1.78 eV perovskite cells reported.We have also achieved 23% cell efficient monolithic perovskite-OPV tandem withan impressive fill factor of 84%, which is the highest for perovskite-OPVtandem cells reported to-date.

卤代多环芳烃用于孔选择层/过氧化物界面改性和钝化，以实现具有创纪录填充因子的高效过氧化物-有机串联太阳能电池

使用有机光伏技术（OPV）制造双结的过氧化物电池的效率可达 40% 以上。然而，仍有改进的余地，如更好的电流匹配、更高的填充因子，以及降低顶部包晶石电池的电压和填充因子损耗。在此，我们利用一种新型卤代多环芳烃化合物--1-萘基氯化铵（NA─Cl）来解决与顶部包晶石电池相关的问题，该化合物具有双重作用，一是对空穴选择层（HSL）进行表面修饰，二是对 HSL/ 包晶石界面进行钝化。X 射线光电子能谱和密度泛函理论计算的结果表明，NA─Cl 保留了 HSL 的自组装特性，同时表现出很高的偶极矩和极化性。这就在 HSL/perovskite 界面上产生了表面偶极，将空穴萃取的能量势垒降低了 210 meV，从而提高了器件的电压输出和填充因子。在高带隙（1.78 eV）过氧化物太阳能电池中采用这种方案后，效率达到了 19.7%，填充因子达到了 85.4%，是目前报道的 1.78 eV 过氧化物电池中最高的。

期刊介绍： ACS Sensors is a peer-reviewed research journal that focuses on the dissemination of new and original knowledge in the field of sensor science, particularly those that selectively sense chemical or biological species or processes. The journal covers a broad range of topics, including but not limited to biosensors, chemical sensors, gas sensors, intracellular sensors, single molecule sensors, cell chips, and microfluidic devices. It aims to publish articles that address conceptual advances in sensing technology applicable to various types of analytes or application papers that report on the use of existing sensing concepts in new ways or for new analytes.
