Antiferroelectric-to-Ferroelectric Switching in CH3NH3PbI3 Perovskite and Its Potential Role in Effective Charge Separation in Perovskite Solar Cells

Sewvandi, GA; Hu, D; Chen, C; Ma, H; Kusunose, T; Tanaka, Y; Nakanishi, S; Feng, Q [Article-Full-text]

Perovskite solar cells (PSCs) often suffer from large performance variations which impede to define a clear charge-transfer mechanism. Ferroelectric polarization is measured numerically using CH3NH3PbI3 (MAPbI3) pellets ...
Controlling dye coverage instead of addition of organic acid to reduce dye aggregation in dye-sensitized solar cells

Sewvandi, GA; Kakimoto, M; Chen, C; Hu, D; Abeygunawardhana, PKW; Feng, Q [Article-Full-text]

The photo-generated electron injection yield of dye-sensitized solar cells (DSSCs) based on donor-acceptor conjugated dyes is lowered by the aggregation of surface adsorbed organic dyes that pose a low-photoenergy conversion ...
Facile size-controllable synthesis process, bandgap blue shift, and enhanced photocatalytic performances of [111]-faceted anatase TiO2 nanocrystals

Xu, L; Sewvandi, GA; Uemura, S; Kusunose, T; Nakanishi, S; Feng, Q [Article-Full-text]

The facet exposed on a nanocrystal surface strongly affects the physicochemical properties of the crystal surface but it is not easy to control in the synthesis process. Herein we demonstrate a facile synthesis process for ...
One-Dimensional Piezoelectric BaTiO3 Polycrystal of Topochemical Mesocrystal Conversion from Layered H2Ti4O9·H2O Single Crystal

Hu, D; Miao, L; Zhang, Z; Li, L; Wang, Y; Hualei, C; Feng, Q; Fan, M; Zhao, L; Sewwandi, GA [Article-Full-text]

A one-dimensional (1D) piezoelectric BaTiO3(BT) polycrystal with a tetragonal system was controllably prepared using a one-step hydrothermal soft chemical process. A layered H2Ti4O9·H2O (HTO) single crystal was used as the ...
Rod-like incipient ferroelectric SrTiO3 polycrystal with crystal-axis orientation

Zhang, Z; Miao, L; Yao, M; Li, L; Zhao, F; Gu, H; Han, Y; Galhenage, AS; Feng, Q; Yang, D; Wang, X; Hu, D [Article-Full-text]

Strontium titanate (SrTiO3, ST) is an incipient ferroelectric material. Generally, a one-dimensional (1D) ST polycrystal is difficult to obtain because of its high aspect ratio and directional orientation. We prepared a ...
Topological relations and piezoelectric responses of crystal-axis-oriented BaTiO3/CaTiO3 nanocomposites

Hu, D; Niu, X; Ma, H; Zhang, W; Sewvandi, GA; Yang, D; Wang, X; Wang, H; Kong, X; Feng, Q [Article-Full-text]

2D crystal-axis-oriented mesocrystalline BaTiO3/CaTiO3 (BT/CT) nanocomposites with high-density heteroepitaxial interfaces were synthesized by a two-step solvothermal soft chemical process. The nanostructures, formation ...
