Uses Of Solar Cell: Definitions, Advantages, Disadvantages & Sample Questions

Ans. The smallest unit of a solar power device is termed a solar cell. A solar cell is also known as a photovoltaic cell. The solar cells are large-area semiconductor diodes due to the photovoltaic effect and light energy is converted into electric current. The solar-powered photovoltaic panels convert rays of the sun into electricity. The majority of solar cells are fabricated from silicon. These solar cells do not require chemical reactions or fuel to produce electric power. 

Ans. A solar cell is also known as a photovoltaic cell.

Ans. The principle of solar cells is understood as: when light enters the junction of p-n, via a very thin p-type film, light photons quickly penetrate the junction. Light energy, in the form of photons, provides the junction with ample energy to create a sequence of electron-hole pairs.

Ans. The properties of solar cells are as follows: 

• Open circuit voltage of the solar cell
• Short circuit current
• Maximum power
• Efficiency

Ans. Uses of the solar cell are specified below:

• A solar cell is used to provide power to rural schools and hospitals. Batteries are charged during the day and used at night for different purposes. 
• Solar energy is even used in cars. The electricity is transferred to the storage battery or powers the motor. 
• Solar cells are used in calculators, watches, clocks, small lights, and even small home appliances. The utility of solar cells can be used in different domains.
• Solar cells are great to help households with different purposes such as bathing, washing clothes, dishwashing, etc. This energy can easily be stored in batteries for emergencies and power cuts.

Ans. With the use of solar panels to generate electricity, no greenhouse gas is emitted into the environment. And the energy produced by the sun is used. The solar-powered electricity is a very effective source of energy 

Ans. The advantages of solar cells are:

•  Solar energy is renewable and sustainable.
• We dint have to refill any fuel to access.
• Saves money and reduces electricity bills. 
• Maintenance is simple and affordable
• Best alternatives for non-renewable energy

Ans. The sun provides clean and pure energy to solar power systems. The installation of solar panels in homes reduces both greenhouse gas pollution and our mutual dependency on fossil fuels. Fossil fuels like coal and some natural gases are the basis of conventional energy.

Ans. The disadvantages of solar cells are:

• Requires sunny weather to work best.
• The manufacturing of solar panels is harmful to the environment.
• The energy conversion rate is low.
• Solar panels are fixed at their installed location and are difficult to relocate.
• We cannot use solar cells at night.

Ans. The best way to utilize the power of solar cells is by using them in villages. The power of the sun can be harnessed to light up the remotest villages where electricity has not been reached yet. The uses of photovoltaic cells can be perfectly understood when the lights turn up after the sunsets.
