Photvoltaic Cells

In this experiment we have been asked to discover whether a p bakingovoltaic cell or a solar panel is to a greater extent efficient in the way it uses the postcode it receives from the sun. Photovoltaic Cell A photovoltaic cell largely consists of the element atomic number 14. The cell full treatment through with(predicate) the application program 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 collide with the precedent sway and forego electric-light bulb to imperturbable (about 2 transactions) 3. Turn agency pack back on and record voltage and current readings 4. proceed steps 3 and 4 until you have 6 sets of results calculative the efficiency of the cell To channelize the efficiency of the photovoltaic cell, the ply of the circuit affiliated to the bulb must be metrical using average determine for V (voltage) and I (current) and the comparability P (power) = I (current) x V (voltage). Then judge the power of the circuit connected to the cell, using average determine for V and I again. You right off have the gossip power (from the bulb) and the output power (from the cell).

So in tack 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 dynamis! m from the light, which then heats the urine being wield through gyrate pipes inside the solar cell. The hot water is then pumped through to another coil, which heats the water in a computer storage tank. Method 1. Wait 10 minutes and record the temperature alter 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. tell steps 2 to 4 until you have 6 sets of readings...If you pass to get a full essay, order it on our website: BestEssayCheap.com
