Q: What are photovoltaic (PV) cells? A: Photovoltaic cells are semiconductor devices which convert sunlight directly into electricity.

Q: How do photovoltaic cells work? A: Photovoltaic cells use the photovoltaic effect to convert sunlight into electricity. When exposed to sunlight, the electrons in the cell are activated and leave the outermost layer of the cell, creating an electrical current.

Q: What are the benefits of photovoltaic cells? A: Photovoltaic cells are beneficial because they produce electricity with no harmful pollutants or noise. They can also be used to store energy for later use, making them a more sustainable energy source.

Q: What is the efficiency of photovoltaic cells? A: The efficiency of photovoltaic cells depends on the type and quality of cell used. Generally, the highest efficiency rates range from 15-22%.

Q: How do hostile environments affect photovoltaic cells? A: Hostile environments can significantly reduce the efficiency of photovoltaic cells due to the high temperatures, humidity and dust which can accumulate on the cells and reduce their output.

Q: How long do photovoltaic cells last? A: Photovoltaic cells typically last between 25-30 years.

Q: Are photovoltaic cells expensive? A: The cost of photovoltaic cells varies depending on the type, quality and quantity purchased. However, prices have generally been decreasing due to advances in technology.

Q: What is the maximum voltage output of photovoltaic cells? A: The maximum voltage output of photovoltaic cells varies based on the type of cell. Some cells can output up to 36 volts, while others can output up to 60 volts.

Q: What is the maximum power output of photovoltaic cells? A: The maximum power output of photovoltaic cells also varies depending on the type and quality of cell used. Some cells can output up to 180 watts, while others can output several kilowatts.

Q: Are photovoltaic cells environmentally friendly? A: Yes, photovoltaic cells are an environmentally friendly form of energy production, as they produce no emissions and are sustainable.
