Question

Statement given below is incorrect. Write the correct statement.
Solar cells are used for providing a large amount of electricity to electrical devices.

Answer 1

Hint:Solar cells are also called photovoltaic cells; it is a device which converts light energy into electrical energy by photovoltaic effect. Photovoltaic effect is a chemical and physical process. So, using this information we will get our required answer.

Complete step by step answer:
We know that, Solar cells convert light energy into electrical energy by photovoltaic effect. There are many advantages of solar cells such as solar cell panels, which are used for heating water and are placed in the rooftops of households, factories, etc. Solar cells are not used for providing a large amount of electricity to electrical devices. It provides less amount of electrical energy to electrical devices.

Thus, the given statement is incorrect, the correct statement would be “Solar cells are used for providing a smaller amount of electrical energy to electrical devices.”

Additional Information:
With numerous pros, solar cells also have many cons. Let us check the disadvantages of solar cells.
1. The initial cost of purchasing and installing solar cells is very high.
2. It totally depends upon the weather. Though solar energy can be collected during rainy or cloudy days, the efficiency of energy drops.
3. It uses a lot of space altogether.
4. There are two ways of using solar energy, either to use it right away, or to store in large batteries, and those cost a lot.

Note:There are many uses of solar cells such as, providing electrical energy to satellites and space probes, providing electrical energy to street lights, lighthouses, etc.
When solar cells are attached in a group, connected in a particular pattern to produce magnitude of current, is called solar panel, it produces a larger amount of electrical energy and can be used for various purposes.
