This work presents to date results of the JOULE project ASPIRE. The goal is to demonstrate practical feasibility of silicon solar cells for use as primary irradiance references in the field of photovoltaics. The underlying principle is the attainment of quasi-constant and near unity valued internal quantum efficiency over a wide central wavelength range. After theoretical design, industrial production processes have been defined and corrected. Results are presented for samples from both pilot series showing accordance with the declared goals. A novel procedure to quantify deviations from the central 100% internal quantum efficiency is also presented. The relevance resides in its ability to provide an autocalibration tool.
