Sensitized Solar Cells

Novel types of solar cells based on nanostructured materials are intensively studied because of their prospective applications and interesting new working principle – essentially due to the nanomaterials used They have evolved from dye sensitized solar cells (DSSC) in the quest to improve their behavior and characteristics. Their nanocrystals (ca. 10-50 nm) do not generally show the confinement effect present in quantum dots of size ca. 1-10nm where electron wave functions are strongly confined originating changes in the band structure. Nonetheless, the nanocrystalline character of the semiconductor used determines a different working principle; which is explained, although it is not completely clear so far,. Different solid nanostructured solar cells are briefly reviewed together with research trends. Finally, the influence of the photoelectrode electron-extracting contact is analyzed.

ABSTRACTA novel approach to synthesize highly luminescent graphene quantum dots (GQDs) with well-defined sizes was explored based on simple oxidation of herringbone-type carbon nanofibers (HCNFs) and size-selective precipitation. In addition, the upconversion properties of GQD were investigated by applying GQD in working electrode of dye-sensitized solar cells (DSSCs).

Sensitized Solar Cells

Solar energy is an abundant and accessible source of renewable energy available on earth, and many types of photovoltaic (PV) devices like organic, inorganic, and hybrid cells have been developed to harness the energy. PV cells directly convert solar radiation into electricity without affecting the environment. Although silicon based solar cells (inorganic cells) are widely used because of their high efficiency, they are rigid and manufacturing costs are high. Researchers have focused on organic solar cells to overcome these disadvantages. DSSCs comprise a sensitized semiconductor (photoelectrode) and a catalytic electrode (counter electrode) with an electrolyte sandwiched between them and their efficiency depends on many factors. The maximum electrical conversion efficiency of DSSCs attained so far is 11.1%, which is still low for commercial applications. This review examines the working principle, factors affecting the efficiency, and key challenges facing DSSCs.
