The Effect of Wavelength of Light on Solar Electrical Performance
Abstract. The photovoltaic effect takes place at the junction of two semiconducting materials. The relation between energy (E) of light (photons) and wavelength (lambda) is given the energy of the incident photons is inversely proportional to their wavelengths. Violet is the Short-wavelength radiation, occupy the end of the …
