In this presentation, we report a simple and effective method for improving the performance of CH3NH3PbI3 perovskite solar cells. By employing a novel hot-air annealing process (HAAP) and a merged annealing method (MA) for preparing the perovskite CH3NH3PbI3 film, we could successfully enhance the crystallinity of the CH3NH3PbI3 active layer and improve its photon collection properties. This led to...
Photovoltaic solar cells have been spotlighted with the growing demands of green and clean energy. Especially, since Oregan and Gratzel reported mesoporous TiO2 electrode dye sensitized solar cells (DSSCs) in 1991, the related works have been widely reported for the enhanced performance. Dyes with high adsorption coefficient and electrolyte with more stability need to be considered for improving DSSCs...
Gd2O3:Eu3+, Tb3+ and Bi3+ ions co-doped Gd2O3:Eu3+, Tb3+ powders were synthesized by solvothermal reaction method. The crystalline structure, surface morphologies and phase transitions of these powders were investigated according to annealing process by using X-ray diffraction (XRD), field emission-scanning electron microscopy, photoluminescence spectroscopy (PL) and transmission electron microscopy...
Y3Al5O12:Eu3+ powders were synthesized by a high-energy ball mill and characterized. The effects of the crystal size on the crystallinity, morphology, structure and luminescence spectra were investigated by X-ray diffraction, field emission-scanning electron microscopy and photoluminescence spectroscopy (PL). Compared to the solid state reaction method, synthesis by high-energy ball milling is simple,...
In this paper, CaSnO3:Eu3+nanocrystals were prepared by hydrothermal synthesis method. The influence of different molar ratio of Ca:Sn on structure of CaSnO3:Eu3+ was investigated by using X-ray powder diffraction (XRD). Well-crystallized and phase-pure CaSnO3:Eu3+ particles of ~90nm in size can be readily obtained at 900??C. Furthermore, photoluminescence characterization of the Eu3+-doped CaSnO3...
