Construction and Working of Photovoltaic Cell


Understanding how photovoltaic cells turn sunlight into electricity is important. These cells have a core made of semiconductor material, usually silicon. Silicon is used in about 95% of all solar modules. Not only do these cells last more than 25 years, but they also keep over 80% of their efficiency. Knowing how they work is key to understanding solar energy.

To make a photovoltaic cell, an electric field is created in a block of silicon. By adding other materials to the silicon, we get two layers with different charges. One layer is positive and the other is negative. These layers are essential for the cell to work. When light hits the cell, it makes electrons move. This motion creates electric current, which is then used as power. Fenice Energy uses this tech to provide stable energy.

The impact of PV cell advancements on the energy sector is huge. For example, perovskite solar cells have gotten much better fast. They went from 3% efficiency in 2009 to over 25% in 2020. Organic cells are not as efficient as silicon ones but are cheaper to make. Multijunction cells are over 45% efficient. They’re great for space missions. Quantum dot cells are easy to make but hard to connect, which lowers their efficiency.

The simplest silicon solar cell can make up to 0.6 volts. The cost of solar systems has dropped a lot too. In the US, prices went from INR 372.6 per watt in 2014 to INR 71.6 in 2020. This makes solar energy much more accessible.

Fenice Energy has over twenty years of experience. They not only know the photovoltaic cell diagram well but also use the latest tech. This ensures the energy they produce is clean and helps the environment.
