“…Light scattering, transmission, and reflection of the active layers of these solar cells can be considerably more complicated compared to conventional homogenous thin film solar cells. 1,2,9 Complicating the optical physics of nanostructured solar cells is the fact that the cells have morphological features with length scales that are for some features less than, and for other features equal to or greater than the wavelength of visible light.…”

A new type of photovoltaic cells is described. The DSSC is modeled using the analytical solution for the semiconductor transport equations of the simple diode. The model includes the effect of the cell shunt conductivity (σ sh ) and series resistance of the cell (R ser ). The solar cell parameters are extracted from experimental results under different illumination levels. The cell parameters are characterized in terms of illumination intensity. The results show a good agreement of the model to fit the experimental data. Current-voltage characteristics, efficiency and fill factor of the DSSC are investigated at different illumination levels.Introduction :

Photocatalytic and photoelectrochemical approaches to solar hydrogen production in our group were introduced. In photocatalytic water splitting system using NiO x / TiO 2 powder photocatalyst with concentrated Na 2 CO 3 aqueous solution, solar energy conversion efficiency to H 2 and O 2 production (STH efficiency) was 0.016%. In addition, STH efficiency of visible light responding photocatalyst, NiO x / promoted In 0.9 Ni 0.1 TaO 4 , was estimated at 0.03%. In photoelectrochemical system using an oxide semiconductor film phptoelectrode, STH efficiencies of meosporous TiO 2 (Anatase) , mesoporous visible light responding S-doped TiO 2 (Anatase) and WO 3 film were 0.32-0.44% at applied potential of 0.35 V vs NHE, 0.14% at 0.55 V and 0.44% at 0.9 V, respectively. Finally, solar hydrogen production by tandem cell system composed of an oxide semiconductor photoelectrode, a Pt wire counter electrode and a dye-sensitized solar cell (DSC) was investigated. As photoelectrodes, meosporous TiO 2 (Anatase), mesoporous S-doped TiO 2 (Anatase), WO 3 , BiVO 4 and Fe 2 O 3 film were tested. STH efficiency of tandem cell system composed of a WO 3 film photoelectrode, and a two-seriesconnected DSC (Voc = 1.4 V) was 2.5-2.8%. In conclusion, it is speculated that more than 5% STH efficiency will be obtained by tandem cell system composed of an oxide semiconductor photoelectrode and a two-series-connected DSC in near future. This suggests a cost-effective and practical application of this system for solar hydrogen production.
