6 FAQs about [What kind of light does a solar cell absorb ]
How do solar cells absorb light?
When photons, particles of light, strike the solar cell, they can be absorbed if their energy matches or exceeds the band gap energy. Shorter wavelengths, such as UV and blue light, carry higher energy photons. Silicon solar cells are efficient at absorbing these shorter wavelengths.
Do solar panels absorb light?
Most solar panels are made of crystalline silicon. It can absorb light in the visible-light spectrum, from 400 nm (violet) to 700 nm (red). This is where high-energy photons are found. Capturing this light well boosts the solar panel’s efficiency. Besides visible light, solar panels can also collect some infrared and ultraviolet light.
Are solar cells efficient at absorbing shorter wavelengths?
Silicon solar cells are efficient at absorbing these shorter wavelengths. Longer wavelengths, including infrared, carry lower energy photons and are less efficiently absorbed by silicon solar cells. Let’s delve into the physics behind it to understand solar cells’ spectral absorbance better.
What is the wavelength of a solar cell?
The wavelengths of visible light occur between 400 and 700 nm, so the bandwidth wavelength for silicon solar cells is in the very near infrared range. Any radiation with a longer wavelength, such as microwaves and radio waves, lacks the energy to produce electricity from a solar cell.
Why is sunlight a part of the solar spectrum?
Sunlight contains an entire spectrum of radiation, but only light with a short enough wavelength will produce the photoelectric or photovoltaic effects. This means that a part of the solar spectrum is useful for generating electricity. It doesn't matter how bright or dim the light is. It just has to have – at a minimum – the solar cell wavelength.
