Solar cells are an alternative method for generating electricity directly from sunlight. With this project, you can get down to the atomic level and learn about the world of solid-state electronics as you investigate how solar cells work. Your experiment will measure the effect of changing light intensity on power output from the solar cell.
Attach the solar cell to a fixed load like a resistor, and repeat the experiment. Calculate the power output of the solar cell (power = current × voltage, or P=IV) under load. How does the power output change with bulb brightness?
It is concluded that when the light intensity gradually increases, the open circuit voltage and short-circuit current of the trough solar photovoltaic cell gradually increase; the open circuit voltage and short-circuit current of the trough solar photovoltaic cell gradually increase.
