Abstract
The increase in pollution and the use of nonrenewable resources in producing electricity has caused the environment to be in danger. The use of dye-sensitized solar cells may help this situation. The purpose of this experiment was to see which solvent extraction of anthocyanin would produce the highest voltage on the dye-sensitized solar cell. It was hypothesized that ethanol would produce the greatest voltage compared to citric acid and distilled water. The experiment was conducted by extracting anthocyanins from Petunia ×atkinsiana plants using the solvents. Then the extraction was used to make a dye-sensitized solar cell. Lastly, a multimeter was used to determine the voltages of each cell from each solvent. Ethanol had the largest voltage compared to citric acid and distilled water. An ANOVA showed that the data were significant; F(2,87)=4775.80, P<0.001. The Tukey tests determined that there were significant differences between ethanol versus citric acid and distilled water, and there were significant differences between citric acid versus distilled water. Therefore, ethanol was the best solvent to make dye-sensitized solar cells since it had the greatest voltage.
