PVE300 Photovoltaic Device Characterisation System provides detector responsivity in unit A/W-nm in the graph Detector responsivity vs Wavelength. But actually by definition and also reported by the researchers in their journal in A/W unit. So, I would like to know how to convert detector responsivity from A/W-nm to A/W unit. Whether, I have to multiply the Wavelength axis to responsivity axis to get it converted and then plotting Detector responsivity vs Wavelength or something else i have to do.
