Abstract
used in experiments for measuring short circuit photo-current and open circuit photo-voltage during normal incidence of monochromatic visible light of wavelengths between 450 and 950 nm from an larrel Asn moaochromator.. A multirange spectra physics 404 radiation power mecer woricing in the same visible
range is used in measuring tne spectral intensity (in^U.Watts
o cm ) and values of the incident photoja flux density H at.
3
J/hV
different wavelengths are calculated using Hc
-2
where J is the intensity of visiule radiation in Watts cm and hV is expressed in joule,
