The Effect of Wavelength on Photovoltaic Cells
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. It arrives at a maximum at about 700 nanometers, makes a series of peaks and dips, and falls abruptly at 1,100 nanometers -- the maximum wavelength for silicon.
