Homogenization and Rapid Oxidation of Spiro‐OMeTAD with Ionic Liquids for Efficient Perovskite Solar Cells

Yi Zhang, Xiuhong Geng, Guohui Luo, Penghui Ren et autres

Abstract Spiro‐OMeTAD is widely recognized as the most effective hole transport layer (HTL) for n‐i‐p perovskite solar cells (PSCs), which typically requires doping with LiTFSI to overcome its low inherent conductivity. However, the doping takes a prolonged oxidation (≈24 h) in an …

Strain Regulation and Defect Passivation of FA‐Based Perovskite Materials for Highly Efficient Solar Cells

Linfeng Zhang, Guohui Luo, Weihao Zhang, Yuxin Yao et autres

Abstract Formamidine lead triiodide (FAPbI3) perovskites have attracted increasing interest for photovoltaics attributed to the optimal bandgap, high thermal stability, and the record power conversion efficiency (PCE). However, the materials still face several key challenges, such as phase transition, lattice defects, and …

Perovskite Surface Passivation Using Thiophene-Based Small Molecules for Efficient and Stable Solar Cells

Weihao Zhang, Min Yuan, Liang Han, Guohui Luo et autres

The suppression of perovskite surface defect recombination is very critical in obtaining high-efficiency perovskite solar cells (PSCs). Ammonium salts with long carbon chains or forming two-dimensional (2D) perovskites are usually used to passivate defects. However, they might limit carrier extraction or transport …

Tunable Hole‐Selective Transport by Solution‐Processed MoO3−x Via Doping for p‐Type Crystalline Silicon Solar Cells

Yaju Wei, Guoqiang Yu, Guohui Luo, Fu Wang et autres

Molybdenum oxide (MoO3−x, x < 3) has been successfully used as an efficient hole‐selective contact material for crystalline silicon heterojunction solar cells. The carrier transport capability strongly depends on its work function, that is, oxygen vacancies; however, there are lack of effective …
