The Basic Research on the Dye-Sensitized Solar Cells (DSSC)

Abstract

Abstract-The dye-sensitized solar cell (DSSC) is a new type of solar cell which converts the visible light into electricity by using the photoelectrochemical system. It is based on the sensitization of the wide band gap semiconductors which is made up of a sandwich-liked structure that consists of a semiconductor formed between a photo-sensitized anode and an electrolyte. In this research, we focused on the TiO 2 photoelectrode by evaluating the particle size of titania, determining the effects of molecular binder PEG towards TiO 2 paste preparation, as well as the effects of natural dye by comparing the blueberry, gardenia blue and yellow and red yeast dye, and evaluating the effect of the multilayer of TiO 2 .

Optimum Conditions for Titanium Oxide Thin Film on Dye-Sensitized Solar Cells Using Organic Dye Sensitizer-MK2

“…It has characteristics of burnout and good solubility in water and ethanol. [16] In this experiment, 0.2g powder, 40ml ethanol and PEG (Wako, average molecular 1500) were mixed with magnetic stirrer. The amount of PEG was 0, 5, 15, 35 or 50 g/L.…”

Natural dyes as photo-sensitizer in solar cells

“…The global energy demand is rocketing, it was 12.7 TW (terawatt, 1 TW = 1012 W) in 1998 but is expected to be 26.4 to 32.9 TW in 2050 and 46.3 to 58.7 TW in 2100 [1]. Since the fossil fuels are nonrenewable and will suffice for merely few decades, solar energy, best option so far, is one of the major viable, eco-friendly, and renewable, alternative source of energy.…”

“…with wide band gap ≥3 eV as photoelectrode and dye molecules as photo-sensitizer. Since natural dyes are more economical, easily attainable, abundant in supply, non-hazardous, eco-friendly, and renewable, fabricating an environment friendly DSSC, more precisely natural dye-sensitized solar cell (NDSSC), are both technically and economically credible alternative to p-n junction silicon solar cells [1]. The objective of this research is to strive n-type doping of ZnO, a semiconductor, with aluminum and observe its optical, structural properties; and their effect on DSSC properties employing natural dye as photo-sensitizer.…”

Enhancement of Dye Sensitized Solar Cell by Adsorption of Graphene Quantum Dots

“…Element of DSSC. DSSC is based on the concept of photosensitization of wide band-gap mesoporous oxide semiconductors [5]. It consists of four main layers, which are electrodes (working electrode and counter electrode), photosensitizer (dye), nanostructured wide bandgap semiconductor layer and electrolyte as shows in Fig.…”
