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

Grégoire Courtine, Yi Ding, Claudia Kathe, Jordan Squair

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 ...

Carbazol-phenyl-phenothiazine-based sensitizers for dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Yi Ding, Wei Huang, Dan Ren, Felix Thomas Eickemeyer, Zhongjin Shen, Yunfei Jiao, Lukas Pfeifer

Heteroaromatic units are commonly used as pi-spacers for sensitizers in dye-sensitized solar cells (DSSCs). Here, we investigated the influence of the pi-spacer on the photophysical properties, electrochemical properties and photovoltaic performance of car ...

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

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

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 ...

Elucidating the role of chlorine in perovskite solar cells

Ulf Anders Hagfeldt, Li Fan, Yi Ding, Jingshan Luo, Xiaoyu Zhang, Di Zhang, Gang Wang

It has been proposed that introducing the chlorine anion into a CH3NH3PbI3 perovskite material can substantially improve the materials properties as well as the solar cell performance. To elucidate the role of chlorine in perovskite solar cells (PSCs), her ...

Enhanced light absorption of thin perovskite solar cells using textured substrates

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

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 ...
