Is electricity produced from solar cell because light has electric and magnetic fields?
Solar cells are made of a semiconductor material, typically silicon, that can absorb sunlight. When sunlight hits the solar cell, it knocks electrons loose from the atoms in the semiconductor material. These electrons then flow through the cell, creating an electrical current.
The electricity produced by solar cells can be used to power devices or stored in a battery for later use. It can also be fed into the grid to supplement or replace traditional electricity sources.
The efficiency of solar cells varies depending on the type of cell and the conditions in which it operates. On average, solar cells have an efficiency of around 15-20%, meaning that they can convert 15-20% of the sunlight that hits them into electricity.
Yes, solar cells can still produce electricity on cloudy days. While they are most efficient in direct sunlight, they can still generate electricity from diffuse light on cloudy days. However, their output will be lower compared to sunny days.
Solar cells produce electricity without emitting any greenhouse gases, making them a clean and renewable energy source. They also do not require water for operation, unlike traditional power plants. By using solar cells, we can reduce our reliance on fossil fuels and help mitigate climate change.
