How do you use a solar cell?

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.

How do solar cells work?

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.

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.

How do you test a solar cell power output?

Test solar cell power output as a function of the angle of the incoming light. Keep the distance and brightness of the light source constant, but vary the angle of the incoming light. Make a graph of your results (power vs. angle). If you've taken trigonometry, see if you can figure out the mathematical function that explains the results.

Who invented solar cells?

In 1883, Charles Fritts described the first solar cells made from selenium wafers. In 1905, Albert Einstein published his paper on the photoelectric effect. In 1914, the existence of a barrier layer in photovoltaic devices is noted.5 In 1916, Robert Millikan provided experimental proof of the photoelectric effect. In 1954,

How does sunlight affect a solar cell?

Sunlight hits the solar cell – if the energy of the photon is high enough (≥band gap energy), it is absorbed on the P-side. This sends the “holes” towards the N-side. A potential difference (voltage) is thereby created across the p-n junction that drives the current and propels the excess free electrons to the conductor on the top of the cell.

Output of a Solar Cell

Measure the open circuit voltage (V oc) across the solar cell. This is the voltage when no current is flowing through the cell. Since no current flows through a perfect voltmeter, a voltmeter measures the open circuit''s voltage. Tilt the solar cell in sunlight or lamplight and notice how the V oc changes. The solar cell measured for the setup shown below, for example, had a V oc = …

1: Basic Characteristics and Characterization of Solar Cells

The power of sun is given in terms of the solar constant, the power spectrum and power losses in earth atmosphere expressed by the so-called air mass. The basic characteristics of a solar cell are the short-circuit current (I SC), the open-circuit voltage (V OC), the fill factor (FF) and the solar energy conversion efficiency (η).

Physics Experiment: Solar photovoltaic cells

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)

Experiments with PV Cells

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.
