Photovoltaic (PV) cells create electricity from sunlight and are one of the true success stories of materials science. Photovoltaic cells have grown from an area of study once viewed with skepticism to a multi-billion dollar market that promises tremendous continued growth.
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.
It is evident from Figure 1 that Isc for a solar cell increases with the increase in the amount of solar radiation incident on the active area of the cell. In this experiment you will investigate the variation of Isc with G for 2 small solar panels connected in series. Each solar panel consists of 12 individual solar cells connected in series.
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. 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.
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. Using equation 2 and the voltage-current values in table 2, calculate the power of the solar cell for each trial.
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,

Good solar sites usually have greater than 2500 KWhm-2 of power available per year. This is the total sunlight power that a square meter of land will receive in one year. Dividing this number by 365 yields about 6.8 KWhm-2 of power per day.The above data shows that there is significant power available in solar energy. The difficulty lies in converting it efficiently and cheaply.
