Why is conversion efficiency important in a photovoltaic cell?

Then the conversion efficiency of a solar cell or panel, is a key parameter of any photovoltaic cell as the more efficient the solar panel is, the more electricity it will produce making it more competitive against other sources of energy generation. Solar energy can be harnessed in one of two primary ways.

What is photovoltaic conversion?

The concept of photovoltaic conversion has been around since the 19th century but gained significant attention in the 1950s with the development of silicon-based solar cells. The efficiency of a solar cell is an important measure of its performance, dictating how much of the incoming solar energy can be converted into usable electrical energy.

How efficient are solar panels?

The efficiency of solar panels has improved dramatically in recent years, increasing from about 15% to more than 20% using newer technologies. High-efficiency solar panels can reach as much as 23% with the power rating of domestic photovoltaic panels increasing from 250W to 370W.

How much power does a 2 m 2 solar panel produce?

A 2 m 2 panel of solar cells has a maximum power output of 400 watts. What would be its conversion efficiency value. Thus the 2 m 2 panel has a conversion efficiency or 20%. That is, 20% of the sunlight hitting the panel is converted into electrical energy, while the remaining 80% is lost.
