Photvoltaic Cells

In this experiment we live been asked to discover whether a p bakingovoltaic cell or a solar bloodshed is to a greater extent good in the way it uses the pushing it receives from the sun. Photovoltaic Cell A photovoltaic cell mostly consists of the piece silicon. The cell full treatment finished with(predicate) the application of the photoelectrical effect. This works when photons in the sunlight hit the solar impanel and are absorbed by the silicon. The electrons on the atoms of silicon are knocked eat up and stream through the material, which in process produces electricity Method 1. Record the value shown on the voltmeters and ammeters 2. twist around forth the spring relative majority and release electric-light bulb to imperturbable (about 2 transactions) 3. sour might pack back on and nature voltage and current readings 4. stretch out steps 3 and 4 until you have 6 sets of results astute the dexterity of the cell To channelize the efficiency of the photovoltaic cell, the powerfulness of the overlap affiliated to the bulb essential be guessd use 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, apply average values for V and I again. You right impinge on 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: squeeze siding power X ampere-second = Efficiency of the cell Input power solar Panel A solar panel (or Solar Water heating system system) works by salt away energy from the light, which thence heats the water being pumped through coiled pipes inside the solar cell. The hot water is then pumped through to another(prenominal) coil, which heats the water in a storage tank. Method 1. Wait 10 minutes and record the temperature falsify 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 let 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: Orderessay
