Development of dye‐sensitized solar cell using M. philippensis (kamala tree) fruit extract: A combined experimental and theoretical study

Abstract

In this work, we have extracted natural dye from the pericarp of Mallotus phillipensis (kamala tree) fruit which is commonly found in East Asia. The natural dye extract has been used such a photosensitizer for dye-sensitized solar cells. Density Functional calculations on one of the major constituent natural dye rottlerin, have been performed to check the properties and applicability of the proposed dye as a photosensitizer and manifested high electron injection efficiency. The best performing device exhibited a power conversion efficiency of 0.55% under 100 mW/cm 2 . This kind of non-toxic and biodegradable natural dye can easily be extracted from an inedible source using a very low-cost technique and therefore it can provide the best alternative to the synthetic dye for solar cells.

Rottlerin-Liposome Inhibits the Endocytosis of Feline Coronavirus Infection

“…The shape of the particles was evaluated by utilizing a transmission electron microscope (TEM), while the size distribution was determined using a dynamic light scattering (DLS) system (Wyatt Technology, Santa Barbara, CA, USA). To determine the amount of R encapsulated in liposome, triton-x100 was mixed with the prepared RL at a ratio of 19:1 to dissolve the lipid ( v / v ), and the absorbance was measured at a wavelength of 405 nm using a spectrophotometer (TECAN, Männedorf, Switzerland) [ 49 ]. The absorbance values obtained were converted to concentrations using a standard curve.…”

Dual Application of Waste Grape Skin for Photosensitizers and Counter Electrodes of Dye-Sensitized Solar Cells

“…Compared to traditional silicon solar cells, dye-sensitized solar cells (DSSCs) have attracted much attention due to their low cost and high efficiency. DSSCs based on wide-bandgap metal oxide semiconductors and redox couple electrolytes are considered a clean and cost-effective way to convert solar energy into electrical energy [ 9 , 10 , 11 ]. A typical DSSC consists of photo-anodes (such as transparent conductive oxides (TCOs) coated with nano-TiO 2 ), counter electrodes, dye molecules that absorb light to produce photoelectrons, and electrolytes containing redox pairs.…”
