Natural Light-harvesting Sensitizers for Dye Sensitized Solar Cell

Catching the rainbow: light harvesting in dye-sensitized solar cells.

Dye-Sensitized Solar Cell for Energy Harvesting Applications

A dye-sensitized solar cell (DSC) has unique properties that the cell performance does not readily decrease even at higher incident light angles compared with a Si solar cell and dose not decrease or rather increases under low light conditions. Fujikura is developing new applications of DSC by taking advantages of these properties to the field of “Energy Harvesting” where rapid growth of market...

Analysis of Natural Sensitizers to Enhance the Efficiency in Dye Sensitized Solar Cell S.Rajkumar

Three vegetable dyes are used for the study: anthocyanin dye from pomegranate arils extract, betalain dye from beet root extract and chlorophyll dye from tridax procumbens leaf. The anthocyanin and betalain, anthocyanin and chlorophyll, betalain and chlorophyll dyes are blended in cocktail in equal proportions, by volume. This study determines the effect of different extraction concentrations a...

Novel quinoxaline-based organic sensitizers for dye-sensitized solar cells.

Novel quinoxaline-based organic sensitizers using vertical (RC-21) and horizontal (RC-22) conjugation between an electron-donating triphenylamine unit and electron-accepting quinoxaline unit have been synthesized and used for dye-sensitized solar cells (DSSCs), leading to the relatively high power conversion efficiencies of 3.30 and 5.56% for RC-21 and RC-22, respectively. This result indicates...

The investigation on different light harvesting layers and their sufficient effect on the photovoltaic characteristics in dye sensitized solar cell

Titanium dioxide-based nanofibers (TiO2 nanofiber) were prepared by an electrospinning technique. The electrospun composite fibers were synthesized at different concentrations of titanium isopropoxide (25.35, 50.69, 76.05 wt%) and calcinated at different temperatures (450 oC, 650 oC and 850 oC) for 2 h. The diameters of nanofibers decreased by increas...
