The effect of Clathrin protein addition on increasing the number of electrons in organic Dye-Sensitized Solar Cell (DSSC)

Abstract

Dye-Sensitized Solar Cell (DSSC) is a solar cell that uses dyes to convert sunlight into electricity, which has a wide absorption spectrum, is inexpensive and environmentally friendly. Visible light sensitive dyes are used in Dye-Sensitized Solar Cell (DSSC) types to generate electricity. Natural sensitive dyes that are commonly used in DSSC are chlorophyll derived from plants. Chlorophyll is a source of electrons which will be excited when exposed to light, resulting in an electric current in the DSSC. The most basic problem in Dye-Sensitized Solar Cell (DSSC) is that the number of electrons produced is still lower than that of silicon solar cells. This is due to the high recombination process of free electrons due to limited diffusion of electrons trapped at the boundary between TiO2 particles caused by less than optimal contact between particles. Clathrin is a protein that plays an important role in the formation of the vesicle layer which is responsible for the transport of molecules in cells. As a protein that plays an important role in the cell transport system, Clathrin can bind to ions in order to transport cells. This study has proven that the addition of Clathrin protein to the DSSC layer can increase the number of electrons generated in the DSSC. The method used in this study was to vary the addition of Clathrin content to TiO2, namely the Clathrin concentration of 0 %, 25 %, 50 % and 75 %. The results showed that increasing the Clathrin content would increase the electric current and the number of electrons generated by the DSSC, namely the 75 % Clathrin content with an electric current of 5,247 mA and the number of electrons was 3.28x1016

Development of dye-sensitized solar cells STEAM learning prototype for supporting educational for sustainable development

“…The price of silicon increases as the demand for the semiconductor industry makes the supply of this raw material increasingly limited [6]. One application of solar cells for converting light energy into electricity with other materials is a solar cell developed by Gratzel, namely Dye-Sensitized Solar Cell (DSSC) [7,8]. The disadvantages of silicone materials can be overcome using dyes or natural dyes, with relatively lower production costs [9].…”

Enhanced mechanical and water resistance properties of cassava starch-PVA composites with TiO2 nanofillers for triboelectric nanogenerators films

“…However, TENG triboelectric nanocomposite films are still dominated by synthetic polymers, which require a complicated, long, and expensive fabrication process. such as; PDMS nanocomposite films with TiO 2 deposition can cause changes in oxygen vacancies on the PDMS surface which can contribute to electron exchange and trapping and have an impact on increasing TENG output power [7], DSSC output power [8], Poly (vinylidene fluoride) (PVDF) polymer with TiO 2 NPs as filler can improve the dielectric properties [9], Polydimethylsiloxane (PDMS) with different TiO x weight ratios as a function of dielectric constant control with 5 % rutile TiO x and 7 % TiO x anatase phase produces TENG output highest ~180 V/8.2 μA and 211.6 V/8.7 μA [10].…”
