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.
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.

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,

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.
