Exp 5 - Lab Report ExampleThe commemorate served as a spacer. One side of taped area was uncoated and an alligator clip could be connected later be connected. The surface of the tape and exposed render was wiped using a tissue soaked in ethanol and the ethanol allowed to evaporate. A small amount of titanium dioxide paste was added and quickly spread by pushing with a microscope slide across the taped surface before the paste dries. The tape gave a spacing of 40-50 micrometers and thus controlled the thickness of the titanium dioxide layer. The tape was carefully removing without scratching the TiO2 coating. The grouch was then heated on a hotplate in a hood for 10-20 minutes until the surface turned chocolate-brown as the organic solvent and surfactant dried and burned glowering to produce a white or green sintered titanium dioxide coating. The glass was allowed to cool slowly. The coating was immersed in raspberry juice for ten minutes until a color change was observed. Remain ing solution and solid was gently rinsed off with water followed by ethanol. A carbon coating was made on the conducting side of the second piece of tin oxide glass by passing it by dint of the candle. The carbon which is located on the perimeter of three sides of the glass plate wiped off using a dry cotton swab. The two coated sides of twain glasses were placed facing each other and held in place using two clips. Triiodide solution was added at the edge of the plate and allowed to spread by dint of the interface. The current and voltage were then metrical.When the dye-sensitized cell was placed in the sun the voltage measured was 3.73 and 3.72 volts which give a power of 930watts and 1193 watts respectively. When placed under the projector the measured voltages were 3.48 and 0.14V corresponding to a power of 97.44 watts and 18.2 watts respectively. From the experiment, it is observed that the highest power output was measured when the solar cell was placed outside in the sun.T he solar cell dexterity is based
