High Excitation Intensity Opens a New Trapping Channel in Organic-Inorganic Hybrid Perovskite Nanoparticles
Zheng, Kaibo; Zidek, Karel; Abdellah, Mohamed; Chen, JunSheng; Chabera, Pavel; Zhang, Wei; Al-Marri, Mohammed J.; Pullerits, Tonu... more authors ... less authors ( American Chemical Society , 2016 , Article)We investigated the excited-state dynamics of CH3NH3PbBr3 perovskite nanoparticles (NPs) and bulk crystals under various excitation intensity regimes using transient absorption spectroscopy. We confirmed the sub-band gap ... -
Tailoring Organic Cation of 2D Air-Stable Organometal Halide Perovskites for Highly Efficient Planar Solar Cells
Chen, Yani; Sun, Yong; Peng, Jiajun; Zhang, Wei; Su, Xiaojun; Zheng, Kaibo; Pullerits, Tõnu; Liang, Ziqi... more authors ... less authors ( Wiley-VCH Verlag , 2017 , Article)2D perovskites have recently been shown to exhibit significantly improved environmental stability. Derived from their 3D analogues, 2D perovskites are formed by inserting bulky alkylammonium cations in‐between the anionic ...
