Light intensity photovoltaic cells

The light intensity on a solar cell is called the number of suns, where 1 sun corresponds to standard illumination at AM1.5, or 1 kW/m 2. For example a system with 10 kW/m 2 incident on the solar cell would be operating at 10 suns, or at 10X.

The Effect of Wavelength on Photovoltaic Cells

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. not on light intensity (amplitude), as wave theory predicted – but on frequency, which is the inverse of wavelength. PV cells are sensitive to light from the entire spectrum as long as the
