In order to answer this question, we must first understand what a solar cell is and how it works. Solar cells are devices that convert sunlight into electricity. They are made of semiconductor materials, such as silicon, that absorb sunlight and create an electric current.
When a solar cell is used to light a street lamp, the solar cell converts the energy from the sunlight into electricity, which is then used to power the street lamp. The solar cell is essentially acting as a power source for the street lamp. The street lamp is able to convert the electricity into light, which allows us to see the street at night.
Solar cells are a very efficient way to convert sunlight into electricity. They are able to convert more than 80% of the sunlight that they absorb into electricity. This makes them an ideal choice for lighting street lamps, as they are able to provide a steady and reliable source of power.

Q: Which energy conversion takes place when a solar cell is used?
A: A solar cell converts energy from the sun into electricity.
Q: What is the energy conversion in a solar light?
A: The light from the sun is made up of tiny packets of energy called photons. When these photons hit a solar cell, they knock electrons loose from the atoms inside the cell. As the electrons flow through the cell, they generate an electric current.
Q: What type of energy transformation is a lamp?
A: The lamp transforms electrical energy into light and heat.
Q: Which energy transformation takes place when you light a candle?
A: The energy transformation that takes place when you light a candle is that the chemical energy in the wax is converted into heat and light energy.
