Dear Colleagues,
Which measurement is more suitable for measuring the intensity of light?
Thank You
Could you be more specific? Are you referring to insolation for PV or thermal collectors, or electric illumination for indoor use? The parameters you want to measure - and therefore the instrumentation used - depend on your application. For energy production, you'd want a pyroheliometer that measures the total energy across all wavelengths, including the infra-red where 1/2 of the sun's energy resides. For illumination, you want an illumination meter that has a spectral response similar to the human eye.
Sorry Sir.. I am working in the field of solar cell.. Hence I want to measure the solar simulator light intensity.How to measure?
Silicon solar cells have a low band gap and are thus able to convert shortwave IR radiation (down to about 1,000 nm I believe) into electricity. You could use either a calibrated silicon PV cell or a pyroheliometer to measure the intensity. A pyroheliometer converts light in all wavelengths to heat - it's effectively an optical calorimeter.
See Conference Paper Solar cell calibration and measurement techniques
for one example of a paper on the relevant discussion.- Badges
