Abstract

An apparatus for determining the spectral response of large area solar cells based on filter method has been introduced. The spectral response of a solar cell is measured by irradiating it by means of a narrow-bandwidth light source at a series of different wavelengths covering its response range, and measuring the short-circuit current density and irradiance at each of these wavelengths. Experiments have been performed to analyze the factors which can affect the spectral response measurements such as the full width at half maximum (FWHM) of filters, the non-uniformity of monochromatic light. The results indicate that less FWHM of filters, more uniformity of monochromatic light will lead to a more accurate measurement.
