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

Ulf Anders Hagfeldt, Jingshan Luo, Chenyi Yi, Zaiwei Wang, 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 ...

Plug-and-play design of current controllers for grid-feeding converters in DC microgrids

Giancarlo Ferrari Trecate, Michele Tucci, Raffaele Soloperto, Renke Han

In this paper, we address the problem of synthesizing decentralized current controllers for grid-feeding converters of current-controlled distributed generation units (CDGUs) in dc microgrids (MGs). Notably, a plug-and-play (PnP) design procedure is propos ...
