dye sensitized solar cells based on a double layered tio2 photoanode consisting of hierarchical nanowire arrays and nanoparticles with greatly improved photovoltaic performance
Journal of Materials Chemistry, 2012Co-Authors: Wuqiang Wu, Jinyun Liao, Hongyan Chen, Xiaoyun Yu, Chengyong Su, Daibin KuangAbstract:A novel double layered photoanode consisting of oriented hierarchical anatase TiO2 nanowire arrays (HNW) and nanoparticles (NP) has been successfully fabricated on a Ti-foil substrate via a two-step hydrothermal and screen-printing process, respectively. Compared to a NP based cell, the photovoltaic performance of the TiO2 HNW cell highlights several outstanding properties, including superior light scattering, rapid electron transport and lower electron recombination rate. Furthermore, the effect of the TiO2 NP film thickness (top layer) on the power conversion of the DSSCs has been investigated in detail. The DSSC based on a Ti/TiO2 HNW + NP Photoelectrode with a total thickness of 31 μm (HNW: 13 μm; NP: 18 μm) shows the highest power conversion efficiency of 7.92%, which is remarkably higher than those of 13 μm HNW (4.52%), 18 μm NP (6.50%) and 31 μm NP (5.99%) Photoelectrodes. The enhancement of the efficiency for the double layered photoanode based cell compared to the single NP is mainly attributed to better light scattering capability, faster electron transport and lower electron recombination for the former.

dynamic study of highly efficient cds cdse quantum dot sensitized solar cells fabricated by electrodeposition
ACS Nano, 2011Co-Authors: Xiaoyun Yu, Jinyun Liao, Daibin Kuang, Chengyong SuAbstract:An in situ electrodeposition method is described to fabricate the CdS or/and CdSe quantum dot (QD) sensitized hierarchical TiO2 sphere (HTS) electrodes for solar cell application. Intensity modulated photocurrent spectroscopy (IMPS), intensity modulated photovoltage spectroscopy (IMVS) and electrochemical impedance spectroscopy (EIS) measurements are performed to investigate the electron transport and recombination of quantum dot-sensitized solar cells (QDSSCs) based on HTS/CdS, HTS/CdSe, and HTS/CdS/CdSe Photoelectrodes. This dynamic study reveals that the CdSe/CdS cosensitized solar cell performs ultrafast electron transport and high electron collection efficiency (98%). As a consequence, a power conversion efficiency as high as 4.81% (JSC = 18.23 mA cm–2, VOC = 489 mV, FF = 0.54) for HTS/CdS/CdSe Photoelectrode based QDSSC is observed under one sun AM 1.5 G illumination (100 mW cm–2).

tri functional hierarchical tio2 spheres consisting of anatase nanorods and nanoparticles for high efficiency dye sensitized solar cells
Energy and Environmental Science, 2011Co-Authors: Jinyun Liao, Bingxin Lei, Daibin KuangAbstract:Hierarchical anatase TiO2 spheres consisting of nanorods and nanoparticles are successfully prepared via a simple acid thermal method using titanium n-butoxide and acetic acid, which will overcome the kinetic and light-scattering limitations of nanoparticles and the surface area limitations of one-dimensional nanostructures, as Photoelectrodes for dye-sensitized solar cells. The as-prepared and calcined hierarchical spheres were characterized by transmission electron microscopy, scanning electron microscopy and X-ray powder diffraction. The DSSC based on hierarchical TiO2 spheres as the Photoelectrode shows a highly efficient power conversion efficiency (10.34%) accompanied by 18.78 mA cm−2 in short-circuit photocurrent density and 826 mV in open-circuit voltage. The great improvements of photocurrent density and power conversion efficiency for hierarchical TiO2 spheres compared to P25 nanoparticle Photoelectrodes are mainly attributed to a considerable surface area, a higher light scattering ability, and faster electron transport rates and slower recombination rates for the former.
