Solar radiation is the energy emitted by the Sun in the form of electromagnetic waves, which travels through space and reaches the Earth. This radiation includes a wide range of wavelengths, known as the electromagnetic spectrum, ranging from radio waves to gamma rays.
The silicon atoms in a photovoltaic cell absorb energy from light wavelengths that roughly correspond to the visible spectrum. The cell has silicon mixed with two different impurities that produce positive and negative charges. Light causes the charges to move, producing an electric current.
Electromagnetic Radiation: The energy emitted by the Sun travels through space as electromagnetic radiation. This radiation includes a wide spectrum of wavelengths, from infrared to ultraviolet light, with visible light being the most important for solar energy. 3. The Photovoltaic Effect:
Photovoltaic cells are sensitive to incident sunlight with a wavelength above the band gap wavelength of the semiconducting material used manufacture them. Most cells are made from silicon. The solar cell wavelength for silicon is 1,110 nanometers. That's in the near infrared part of the spectrum.
The photovoltaic cell doesn't convert all the light, even if it's at the right wavelength. Some of the energy becomes heat, and some reflects off the cell's surface. If you carefully plot a solar cell's output energy against the wavelength of incoming light, your graph will show a response curve that begins at about 300 nanometers.
