How do solar cells generate 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) expressed mathematically as.

What is solar energy & how does it work?

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.

How can solar energy be converted into 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. This electricity can be stored in batteries or other storage mechanisms for use at night.

How do you measure the efficiency of solar cells?

Measure the efficiency of solar cells as they convert sunlight to power. Solar cells convert light energy into electrical energy. With a few simple tools on a sunny day (or working indoors under a light source), you can measure how efficient a solar cell is at transforming sunlight into electricity. None needed. Investigation 1

How do engineers characterize a solar cell?

Engineers use the theoretical power to characterize a solar cell. The power provided by the sun per unit area, known as solar intensity, is approximately 1,000 Watts per meter squared. This value is reduced by clouds, haze, and when the radiation from the sun has to travel a longer path through the atmosphere (such as at sunset or sunrise).

How do I set up a solar cell experiment?

Set up your experiment, as shown in Figure 1. Set up your lamp a fixed distance from where you will test the solar cell. If you are doing the project outside, set up your experiment in an area with direct sunlight. Connect your multimeter's leads to the solar cell's alligator clip leads.
