Abstract

Researchers are looking for new ways to generate solar energy in a cheaper, safer, and faster method. Anthocyanin pigment photovoltaic cells have been used in solar cells due to their ability to convert light energy into electrical energy. Fruit dyes have been incorporated into photovoltaic cells due to the anthocyanin pigments they contain, but roses, which also contain anthocyanin, have not yet been tested. The purpose of this analysis was to test if anthocyanin pigments from a Rosoideae rosa petal could generate more electricity than a photovoltaic cell made from copper. It was hypothesized that the darker the anthocyanin pigment, the higher the voltage of the cell. This was assumed as darker anthocyanin pigments were proven to have higher concentrations of anthocyanins and have high pH values, which can conduct electricity. Experimentation was accomplished by using rose colors of purple, red, pink, and yellow and using copper as the basis of comparison. The cells containing anthocyanin pigments were created along with a titanium dioxide paste and were put under direct light. The copper cells were made by adding a sodium bicarbonate solution to the copper sheets. A one-way ANOVA test was run to test a difference in the means, and was proven to have a difference at = 0.05 when p = 0.0001. The hypothesis was mostly proven, resulting in the darkest color, purple, having the highest amount of electricity generated, but followed by the copper having the second highest electricity amount, instead of the next darkest color, red.
