Spectral response Clause Samples

Spectral response. 1) The External Quantum Efficiency (EQE) shall be measured under monochromatic irradiation in a wavelength range suitable for the solar cell optical bandwidth, indicatively 0,3 µm ÷ 1,2 µm. 2) The monochromatic irradiation shall be generated by continuous recording through a monochromatic probe based on broadband light source filtered by a monochromator. Typical wavelength sampling is 5 nm. 3) The irradiation intensity at all wavelengths shall be such as to ensure that the measurement is made in the region where the cell response short-circuit current versus irradiance is linear.
