Photovoltaic Cell
A photovoltaic cell mostly consists of the element silicon. The cell full treatment through with(predicate) the application of the photoelectric effect. This works when photons in the sunshine hit the solar panel and are absorbed by the silicon. The electrons on the atoms of silicon are knocked eat up and flow through the material, which in turn produces electricity
Method
1. Record the value shown on the voltmeters and ammeters
2. twist around off the power pack and allow electric-light bulb to imperturbable (about 2 transactions)
3. Turn power pack back on and record voltage and current readings
4. Continue steps 3 and 4 until you have 6 sets of results
Calculating the efficiency of the cell
To channelize the efficiency of the photovoltaic cell, the power of the circuit affiliated to the bulb must be calculated using average values for V (voltage) and I (current) and the equation P (power) = I (current) x V (voltage). Then calculate the power of the circuit connected to the cell, using average values for V and I again. You right off have the input power (from the bulb) and the output power (from the cell).
So in order to calculate the efficiency of the cell, calculate:
railroad siding power
X 100 = Efficiency of the cell
Input power
Solar Panel
A solar panel (or Solar Water Heating system) works by collecting energy from the light, which then heats the urine being pumped through coiled pipes inside the solar cell. The hot water is then pumped through to another coil, which heats the water in a storage tank.
Method
1. Wait 10 minutes and record the temperature change in the water
2. Record V (voltage) and I (current) values for the power system connected to the bulb
3. Turn off the power and allow water to cool (about 10 minutes)
4. repeating steps 2 to 4 until you have 6 sets of readings...If you loss to get a full essay, order it on our website: Ordercustompaper.com
