6 FAQs about [Solar cell waveform]
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.
What is the spectral response of a silicon solar cell?
A spectral response curve is shown below. The spectral response of a silicon solar cell under glass. At short wavelengths below 400 nm the glass absorbs most of the light and the cell response is very low. At intermediate wavelengths the cell approaches the ideal. At long wavelengths the response falls back to zero.
Does a silicon solar cell respond to longer wavelengths?
Silicon's band gap is about 1.1 eV, corresponding (by chance) to about 1.1 um wavelength. Therefore a silicon solar cell will have practically no response to longer wavelengths than 1.1 um, and it would be senseless to measure its response in that band. The solar radiation reaching the earth drops dramatically below about 300 nm:
How do photovoltaic cells work?
Traditional photovoltaic cells turn a relatively small part of the sun's light spectrum into electricity, limiting their efficiency and power output. The cell's silicon material responds to a limited range of light wavelengths, ignoring those that are longer and shorter.
Why do photovoltaic cells have a jagged curve?
The cell's silicon material responds to a limited range of light wavelengths, ignoring those that are longer and shorter. As the wavelength varies from short to long, the cell's output rises and falls in a jagged curve. Newer photovoltaic cell designs achieve higher efficiency by converting more wavelengths into useful energy.
How does a photovoltaic cell convert light?
The photovoltaic cell doesn't convert all the light, even if it's at the right wavelength. Some of the energy becomes heat, and some reflects off the cell's surface. If you carefully plot a solar cell's output energy against the wavelength of incoming light, your graph will show a response curve that begins at about 300 nanometers.
