Our world is facing an environmental crisis that driving scientists to research green and smart solutions in terms of the use renewable energy sources low polluting technologies. In this framework, photovoltaic (PV) technology one most worthy interest. Dye-sensitized solar cells (DSSCs) are innovative PV devices known for their encouraging features cost easy fabrication, good response diffuse l...

in this study, we investigated the effect of using large tio2 nanoparticles in the matrix of small nanoparticles to improve the performance of dye-sensitized solar cells (dsscs), as light scatter to increase the light harvesting. the mixed powder was deposited by electrophoretic deposition (epd) on fto (f-sno2 coated glass). it is shown that adding small quantity of larger nanoparticles can enh...

Advances in solar cell technology require designing of new organic dye sensitizers for dye-sensitized solar cells with high power conversion efficiency to circumvent the disadvantages of silicon-based solar cells. In silico studies including quantitative structureproperty relationship analysis combined with quantum chemical analysis were employed to understand the primary electron transfer mech...

The objective of this investigation was to shed light on the nature of interaction of different organic dyes and an inorganic dye, Ruthenium (II) polypyridine complex, with TiO2 nanoparticles. TiO2 is commonly deployed as an efficient energy transfer electrode in dye sensitized solar cells. The efficiency of dye sensitized solar cells is a function of the interaction of a dye with the electrode...

Oxide nanocrystallite aggregates are candidates for use in dye-sensitized solar cells. The aggregates are of submicron size, formed by nano-sized crystallites and, therefore, able to offer both a large specific surface area and desirable size comparable to the wavelength of light. While used for a photoelectrode in a dye-sensitized solar cell, the aggregates can be designed to generate effectiv...

Solar cells must accomplish two basic tasks to generate current: absorb incident photons and conduct excited electrons to the circuit. Traditional solar cells made of silicon accomplish these with a single, expensive material. Dye sensitized solar cells (DSSC) are an alternative using separately optimized materials for each task. In short, a dye absorbs the photons and injects them into a semic...
