Hydrogenated TiO2 Thin Film for Accelerating Electron Transport in Highly Efficient Planar Perovskite Solar Cells
Jingshan Luo, Yang Li, Xiaoyu Zhang, Yi Ding, Di Zhang
Intensive studies on low-temperature deposited electron transport materials have been performed to improve the efficiency of n-i-p type planar perovskite solar cells to extend their application on plastic and multijunction device architectures. Here, a TiO ...
Wiley2017Enhanced 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 ...
Elsevier Science Bv2017Donor design and modification strategies of metal-free sensitizers for highly-efficient n-type dye-sensitized solar cells
Dye-sensitized solar cells (DSSCs) cannot be developed without the research on sensitizers. As the key of light harvesting and electron generation, thousands of sensitizers have been designed for the application in DSSC devices. Among them, organic sensiti ...
