Single cell atlas of spinal cord injury in mice reveals a pro-regenerative signature in spinocerebellar neurons

Grégoire Courtine, Claudia Kathe, Jordan Squair, Yi Ding

After spinal cord injury, tissue distal to the lesion contains undamaged cells that could support or augment recovery. Targeting these cells requires a clearer understanding of their injury responses and capacity for repair. Here, we use single nucleus RNA ...

Ligand-Modulated Excess PbI2 Nanosheets for Highly Efficient and Stable Perovskite Solar Cells

Ulf Anders Hagfeldt, Jingshan Luo, Zaiwei Wang, Chenyi Yi, Xiaoyu Zhang, Yi Ding, Zhen Yang

Excess lead iodide (PbI2), as a defect passivation material in perovskite films, contributes to the longer carrier lifetime and reduced halide vacancies for high-efficiency perovskite solar cells. However, the random distribution of excess PbI2 also leads ...

Quasi-Heteroface Perovskite Solar Cells

Ulf Anders Hagfeldt, Peng Wang, Yang Li, Xiaoyu Zhang, Yi Ding

Perovskite solar cells (PSCs) have attracted unprecedented attention due to their rapidly rising photoelectric conversion efficiency (PCE). In order to further improve the PCE of PSCs, new possible optimization path needs to be found. Here, quasi-heterofac ...

Enhanced light absorption of thin perovskite solar cells using textured substrates

Jingshan Luo, Yang Li, Xiaoyu Zhang, Yi Ding, Di Zhang, Li Fan

Thin perovskite layers are crucial for fabricating semitransparent perovskite solar cells and tandem devices. However, this will reduce the light absorption of the device, resulting in low efficiency. To overcome this dilemma, we use textured fluorine dope ...
