Do electron absorb the entire photon energy?

AI Thread Summary
Solar panels do not absorb the entire photon energy from the solar spectrum; their absorption depends on the specific type of panel used. Different solar panel technologies, such as single-crystal, amorphous, and polycrystalline silicon panels, exhibit varying absorption spectra. The range of wavelengths absorbed is limited, meaning not all photons contribute to energy conversion. Additionally, the conversion spectrum is typically narrower than the overall absorption spectrum. Understanding these distinctions is crucial for evaluating solar panel efficiency and performance.

I couldn't type the whole question | -or jusg part of the spectrum during the working of a solar panel

I do not understand what this means. Could you elaborate a little more on the question? Solar spectrum consists of photons with various energy. Are you asking if the solar panel would absorb photons throughout the entire spectrum?

Then the answer is no. Though the range of spectrum in which the solar panel absorbs depends on exactly what type of solar panel you are looking at. Even if you say Si-solar panels, there are single-crystal, amorphous, polycrystalline types out there. They all have different absorption spectra. If you are talking about conversion spectrum, then it is going to be even narrower.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
