A solar cell uses the photovoltaic effect to convert solar radiation directly to DC electrical energy. The rate of energy generation or power from the solar cell depends on the amount of solar radiation falling on the active area of the cell. This power output can be calculated from the product of the solar cell current (I) and voltage (V)
When sunlight enters a PV cell, the light can separate an electron from an atom and the electric field helps move the electrons to charge collecting areas. The electrons are then gathered on the surface of the solar cell by a grid of metal connected to a circuit.
Connect the solar cell with the electric motor and a DMM to measure current. Record the solar cell current and observe the turn speed of the propeller of the electric motor. Without changing the desk lamp and solar cell distance, cover the solar cell with a blue filter.
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
Solar energy can be part of a mixture of renewable energy sources used to meet the need for electricity. Using photovoltaic cells (also called solar cells), solar energy can be converted into electricity. Solar cells produce direct current (DC) electricity and an inverter can be used to change this to alternating current (AC) electricity.
Connect the solar cell with the electric motor and a DMM to measure current. Change the angle of the solar cell from 0 to 60. Measure the angle with a protractor. Measure the solar cell current for given angles and observe the turn speed of the propeller of the electric motor. Record the results in table 4.
One method of converting energy from the sun (solar energy) is to use a solar cell also known as a photovoltaic cell. A solar cell uses the photovoltaic effect to convert solar radiation directly to DC electrical energy.
