The Method of Calculating the Spectral Sensitivity of Solar Cells

A new method for calculation the spectral sensitivity of solar cells based on data obtained by measurement of differential sensitivity. As follows from the conducted analysis, measurements of cells can be carried out only at a constant spectral composition of background radiation. In particular with a single powerful lamp is repositionable relative to the cell. In the practical application of the method is expected to increase the accuracy of determining the spectral sensitivity, especially in the region of large wavelengths, where there is the maximum nonlinearity of the dependence of a current on irradiance.
