A vast array of colorants obtained from natural sources such as plants, insects/animals and
microbes have been scrutinized in recent past for their use in different kinds of applications …

This review describes the work which has mainly been developed in our laboratory on
photoelectrochemical solar cells and on electrochemical devices in which suitable dyes are …

Blue-violet anthocyanins from Jaboticaba (Myrtus cauliflora Mart) and Calafate (Berberies
buxifolia Lam) were employed as TiO2 dye-sensitizers. Solar cells sensitized by Jaboticaba …

Many tropical fruits are rich in anthocyanins, though limited information is available about
the characterization and quantification of these anthocyanins. The identification and …

Dye-sensitization of nanocrystalline n-type TiO2 was achieved by using fruit extracts as a
natural source of sensitizers. Fresh extracts of chaste tree fruit (“maria-preta”, Solanum …

Study on dye-sensitized solar cells (DSSCs) with extracts of Canna indica L., Salvia
splendens, Solanum nigrum L. as sensitizers is firstly reported in this paper. DSSCs were …

Carbon nanotube (CNT) films have been used as counter electrodes in natural dye-
sensitized (anthocyanin-sensitized) solar cells to improve the cell performance. Compared …

Annona crassiflora Mart. is a typical fruit of the Brazilian cerrado, considered to be a species
of economic interest, mainly for its use in cooking, which is widespread among the …

Dye-sensitized solar cells, named by us Dye-Cells, are one of the most promising devices
for solar energy conversion due to their reduced production cost and low environmental …

Natural dyes composed by anthocyanins extracted from natural Caribbean species S.
cumini, were employed to evaluate their effects on the photocatalytic properties of TiO 2 thin …
