Four natural dyes were extracted from different fruits used in the Dye-sensitized solar cell (DSSC). It includes ber, blackberry, black grapes, and blueberry by individual dye or combined with other dyes. The solution's absorption spectra extended to whole visible region 200–750 nm. FTIR spectroscopy was employed identify possible functional group vibrations responsible for dyes' chemical activ...

dye-sensitized solar cells present promising low-cost alternatives to the conventional silicon (si)-based solar cells. the counter electrode  generally consists of pt deposited onto fto plate. since pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. carbon nanotubes  have shown significant properties such...

Multi-walled carbon nanotube (MWCNT)/TiO2 mesoporous networks can be employed as a new alternative photoanode in dye-sensitized solar cells (DSSCs). By using the MWCNT/TiO2 mesoporous as photoanodes in DSSC, we demonstrate that the MWCNT/TiO2 mesoporous photoanode is promising alternative to standard FTO/TiO2 mesoporous based DSSC due to larger specific surface area and high electrochemical act...

Indacenodithiophene-core-based D–π–A-type organic sensitizers with two different donor antennas (triphenylamine and phenothiazine) were designed synthesized for use as light-harvesting materials in dye-sensitized solar cell (DSSC) applications.

Four key parameters namely light trapping, density of light harvesting centre, photoinduced electron injection and electron transport without self-recombination are universally important across all kinds of solar cells. In the present study, we have considered the parameters in the context of a model Dye Sensitized Solar Cell (DSSC). Our experimental studies reveal that carbonate doping of TiO2...

Almost all types of solar cells suffer from a decreased power output when the incident light is tilted away from normal since the incident intensity generally follows a cosine law of the incident angle. Making use of the blue shift nature of the Bragg position of a TiO2 nanotube photonic crystal (NT PC) under oblique incidence, we demonstrate experimentally that the use of the NT PC can partial...

in order to fabricate transparent tio2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from ti substrate by a re-anodization method. the membranes are transferred on fto glass by two different methods. at the first one, 100mm ti-isopropoxide is used to make tio2 nanoparticles for adhering tio2 nanotube membranes to fto and in the second one a commercial ti...

Three natural dyes, extracted from leaves of mangifera indica, manihot esculenta and hibiscus sabdariffa were used as sensitizers to fabricate dye-sensitized solar cells. The Sensitization performance related interaction between the dyes titanium (iv) oxide (Ti02) surface evaluated under 100mW/cm2 light intensity. photoelectrical DSSCs based on these show that V0c ranged 0.300 0.477V Jsc was in...
