Experiment 5 - Lab Report ExampleThe solar cubicles are not only cheap, but they are also safe for the environmental use because they do not result in pollution.In electrolyzing water using solar energy, dye-sensitized p white-hotovoltaic cells are used. The sensitizer absorbs light that excites the chromophore leading to the production of electrons that undergo a series of processes within the cell to produce galvanic current for electrolyzing water. It is hypothesized that dyes or quantum dots can be used to sensitize the semiconductor oxide films of a solar cell to generate electricity (Gratzel 6841). Thus, this try aims to construct a dye-sensitized solar cell and to measure its current and potential difference as well as using the cell to convert light into electricity for electrolysis of water.The materials indispensable for this experiment include a multimeter for measuring resistance, a candle flame for producing carbon powder, and a piece of outfit for connecting glass layers. Two pieces of glass and a piece of tissue paper are also required. The chemicals included ethanol for removing dirt on the surfaces of the glass, anthocyanin dye, titanium dioxide paste, potassium triiodide (KI3) electrolyte. In addition, a lab coat, goggles, and tongs were required for safety reasons.We assembled the cell in the first lab session and determined the current and voltage. During this process, we identified the conducting view of a tin-oxide piece of glass by a multimeter and wiped off the surface with an ethanol-moistened tissue to remove dirt. We hence added a small amount of titanium dioxide paste and heated the glass on a hot plate in a hood for 20 minutes until it turned green. On cooling to way of life temperature, we introduced anthocyanin dye. We coated the second piece of tin oxide glass with carbon powder by passing it done a candle flame. After which, we assembled the two glasses by putting the coated sides together
