Determination of the Efficiency of Photovoltaic Converters Adequate to Solar Radiation by Using Their Spectral Characteristics

The paper presents experimental studies of silicon photovoltaic solar radiation converters. An experimental evaluation of the photoconversion efficiency is considered, the spectral dependences of the current photoresponses of the photoelectric converter are determined and the spectral densities of the current photoresponses of various photovoltaic converters from an artificial light source are compared. Based on the results obtained, it becomes possible to determine the efficiency of the photovoltaic converter for a given wavelength of monochromatic radiation, as well as to calculate the efficiency of the photovoltaic converter for a given radiation spectrum.
