Based on some physical and geometric parameters, the influence of internal resistance on the cell performance is analyzed and a semi-empirical mathematical model of the efficiency is built for some configurations of large-scale dye-sensitized solar cells. Three configurations of large-scale cells are investigated, in which the independent units are connected in series and in parallel, as well as in series-parallel. The efficiencies of the three-type large-scale cells are calculated according to their physical and geometric parameters. The applicability of the model is analyzed by comparing the calculated efficiencies with the measured ones. The influences of the physical and geometric parameters on the cell performance are investigated based on the semi-empirical mathematical model. It is found that the optimization of the performance of large-scale cells can be carried by analyzing the influences of physical and geometric parameters using the semi-empirical mathematical model. © 2012 Chinese Physical Society.

In the present study, molybdenum phosphide (MoP), nickel phosphide (Ni5P4), and carbon-supported Ni5P4 (Ni5P4/C) were proposed for use as counter electrode (CE) catalysts in dye-sensitized solar cells (DSCs) for the regeneration of both the conventional I3−/I− redox couple and a new organic T2/T− redox couple. For the I3−/I− redox couple, the DSCs using MoP and Ni5P4 CE yielded a power conversion efficiency (PCE) of 4.92 and 5.71%, and the DSC using Ni5P4/C showed a high PCE of 7.54%, which was close to that of the DSC using Pt CE (7.76%).

Three nanomaterials, namely, titanium carbide (TiC), tungsten oxide (WO2), and vanadium nitride (VN), are introduced into dye-sensitized solar cells (DSCs) as counter electrode (CE) catalysts to replace the expensive Pt CE. Three kinds of substrates of bare glass (BG), Ti foil, and polyimide (PI) film are applied as F-doped tin oxide (FTO)-free substrates for rigid and flexible DSCs; thus realizing FTO-free and Pt-free CEs simultaneously in the DSC system. A carbon layer is used as an electron collector to replace the expensive FTO conductive layer in the insulative BG and PI film. Cyclic voltammetry, electrochemical impedance spectroscopy, and Tafel polarization curves are performed to compare the catalytic activities of these CEs for the reduction of triiodide to iodide.

Dye-sensitized solar cell (DSC) is considered as the third generation photovoltaic cell. To commercialize DSCs successfully, it is necessary to further improve the efficiency. One of the effective methods is improving the utilization ratio of the solar light and broadening the absorption spectra of the cell. Tandem dye-sensitized solar cells (TDSC) have attracted much attention due to their novel structure and particular characteristics. In this review, the research background and the recent progress of TDSC at home and abroad are summarized. The traditional TDSC, N-P type TDSC, hybrid DSC and the tandem cells based on the other type solar cell and DSC are introduced in detail. The recent progress and the existent problems are discussed. Furthermore, the structures, characteristics and efficiencies of every type tandem solar cells are analyzed. At last, the development tendency and promising prospects of TDSC are presented.

Highly efficient large scale flexible dye-sensitized solar cells (DSCs) were successfully designed and fabricated. By the introduction of a light scattering layer or pressure, the DSC efficiency was greatly improved. The flexible DSCs with a small surface area (0.4 cm × 0.4 cm) gave a high energy conversion efficiency of 5.50%. The energy conversion efficiencies of large area DSCs (2 cm×3 cm, active area of 2.7 cm2) improved from 1.52% to 1.81% and 2.50%, which is an increase of 20.0% and 66.7% compared with the DSCs prepared without any treatment. The 5 cm×7 cm DSCs (active area of 16.2 cm2) without any optimization showed an energy conversion efficiency of 1.60% under a sunlight intensity of 40 mW·cm-2. The mechanism for the improvement in efficiency was also studied. The results of electrochemical impedance spectroscopy (EIS) demonstrated that the pressure method can significantly reduce the series resistance (Rs) and the charge transfer resistance (Rct) in the TiO2/dye/electrolyte interface. Scanning electron microscopy (SEM) showed that the TiO2 particles were far more closely connected after pressing, which was helpful for electron transport in the TiO2 network as well as for dye adsorption. In addition, the photovoltaic parameters of these flexible DSCs were found to be stable after the 900 h stability tests. The experimental results obtained for these flexible DSCs can be used as a foundation for further basic research and for industrialization technical research. © Editorial office of Acta Physico-Chimica Sinica.

The new type of hybrid and tandem dye-sensitized solar cells 査読有り

Dye-sensitized solar cell (DSC) is a new type of photovoltaic cell. To further improve the energy conversion efficiency of DSCs, one method is broadening the absorption spectra and improving the utilization ratio of light. In this paper, three types of tandem DSCs and a new type of hybrid DSC prepared by a film-transfer technique were investigated. The superposition character of tandem DSCs and the influencing factors of the efficiencies of the top and bottom cells in different structure were systematically studied. Then, we investigated the superposition character of hybrid DSC and the mechanism on VOC. The results show that the hybrid structure can achieve a panchromatic response. The superposition of IPCE and JSC were confirmed. The high efficiency of 11.05% was achieved. The high VOC of hybrid DSC was correlated to the different degree of back reactions at the TiO2/dye/electrolyte interface. The highest efficiency of hybrid DSC was achieved when compared with tandem DSC and co-sensitized DSC under the same conditions.

We investigated the effect of varying amounts of N dopant on the performance of dye-sensitized solar cells (DSCs) based on the N-doped TiO2 electrodes. An interesting hierarchically macro-/mesoporous N-doped TiO2 structure with parallel macro-channels was formed by a simple template-free wet method. A series of N-doped TiO2 electrodes with varying N dopant amounts were fabricated for the DSCs.

Due to the energy crisis, it is necessary to develop clean and renewable energy sources. In this study, we report an efficient and economical technology to produce hydrogen from solar energy by splitting water in a two-compartment photoelectrochemical (PEC) cell without any external applied voltage. To enhance the solar conversion efficiency, highly ordered TiO2 nanotube arrays with 4 μm in length were synthesized by a rapid anodization process in ethylene glycol electrolyte. Crystal phase and morphology of the TiO2 nanotubes (NTs) samples annealed at various temperatures were characterized by XRD and FESEM. Transient photocurrent response and linear sweep voltammetry curves were measured using electrochemical working station under solar light illumination. The photocatalytic activity was evaluated by the hydrogen production in the PEC cell. The results indicated that the crystal phase and morphology of TiO2 NTs had no great changes at low annealing temperatures. Anatase phase and tubular structure of TiO2 NTs were stable up to 450 °C. With further increase in temperature, the crystallization transformation from anatase to rutile phase appeared, accompanied by the destruction of tubular structures. Due to the excellent crystallization and the maintenance of tubular structures, TiO2 NTs annealed at 450 °C exhibited the highest photoconversion efficiency of 4.49% and maximum hydrogen production rate of 122 μmol/(h·cm2), which is superior to most of those reported so far. © 2011 American Chemical Society.

Three kinds of N-doped titania (TiO2-xNx) were synthesized by wet methods using ammonia, urea, and triethylamine as nitrogen sources, respectively. The effect of different nitrogen sources on the properties of TiO2-xNx powder and film were investigated in detail. These results show that all three TiO2-xNx are pure phase of anatase. Comparing with pure TiO2 and commercial P25 electrodes, a 17% and 44% improvement in efficiency was realized in dye-sensitized TiO2-xNx solar cells.
