This plot Jsc(x) where x is the intensity of the solar radiation will be more or less linear flow low intensity irradiation. The steps of calculating Jsc given the light intensity F in photons per cm^2/s is given in details in the literature at the link: Conference Paper Generic Analytical Models for Organic and Perovskite Solar Cells
