Abstract
A giant photovoltaic effect was revealed in silicon-type photoelectronic converters (solar cells) coated with specific antireflecting films developed by our research group. More specifically, it was found that the ratio of photoconversion efficiency for a solar cell with such an antireflective film on its surface to the efficiency for a solar cell without the film equals a second power of relation of photoelectromotive force of a converter with the film to the photoelectromotive force of a converter without the film. The film comprises an antireflecting coating that is high-efficient in the wavelength range of 450 to 1000 nm and that is synthesized on the basis of novel nanomaterials that provide the quasi-zero average complex refractive index of nanocomposite film. |
