Question

describe construction and working principles for conversion of solar energy to electrical energy through photo voltaic cell​

Answer 1

Answer:

Working Principle of Solar Cell. When light reaches the p-n junction, the light photons can easily enter in the junction, through very thin p-type layer. The light energy, in the form of photons, supplies sufficient energy to the junction to create a number of electron-hole pairs.

Answer 2

Solar power can be used to generate electricity through photovoltaics or concentrated solar power systems. Solar energy is directly converted to electricity via photovoltaics. They operate on the photovoltaic effect's concept.

Explanation:

• When certain materials are exposed to light, photons are absorbed and free electrons are released.
• Solar power can be used to generate electricity through photovoltaics or concentrated solar power systems.
• Solar energy is directly converted to electricity via photovoltaics.
• They operate on the photovoltaic effect's concept.
• When certain materials are exposed to light, photons are absorbed and free electrons are released.
• Solar panels range in power from a few hundred watts  to a few kilowatts .
• They are available in a variety of sizes and price points.
• Solar panels or modules are designed to provide electric power at a specific voltage , but the current they produce is directly proportional to the amount of light they receive.
• Photovoltaic modules produce DC electricity at this time.
• However, because we demand AC power most of the time, a solar power system must also include an inverter.
