Purpose: The purpose of this lab experiment is to demonstrate the effect of several variables  (distance angle, filters, and shading) on the outpoint of photovoltaic (PV) cells. The power that is generated by the PV cell can be determined with the following equation: P = Iv, where P is  power (Watt), i is current (Ampere), and V is voltage (Volt).  Materials: We connected our  photovoltaic (PV) cell  to the  multimeter . We attached the red and  black  alligator clips to the red and black wires  to the PV cell. We placed our photovoltaic cell  directly below  the ceiling lights  to act as direct sunlight. We used a  measuring tape  to measure  the distance of the PV cell from the light source. We placed different  color filters  over the PV  cell to change the power output of the PV cell. We used a  protractor  to determine the current  and voltage of the PV cell at different angles towards the light source.  Method: First, we constructed the PV cell system by attaching it to the electrical wires with the  alligator clips and the multimeter. We exposed the PV cell to light to see if we were getting a  current and voltage reading. Then, we measured the effect of distance from the light source. We  set the cell up at a desired distance (in inches) from the light source and recorded and the voltage and current readings. We multiplied the voltage by the current to calculate the power output for  each distance. After that, we measured the effect of light filters. We placed the PV cell directly  below the light source and placed 7 different colored filters (red, blue, green, pink, yellow,  orange, and purple) on the cell. Next, we measured the effect of shading. We placed the cell  directly below the light source and placed a thick envelope covering one of the 10 cells. We  subsequently recorded the current and voltage and repeated this procedure until all of the cells on the panel were covered. After, we measured the effect of tilt angle. We placed the cell directly  below the light source and used a protractor to determine the angle. We tilted the panel at 15-

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
