6 FAQs about [How much difference does it make when photovoltaic cells turn red]
How does a photovoltaic cell respond to light?
A photovoltaic cell responds selectively to light wavelengths. Those much longer than 700 nanometers lack the energy to affect the cell and simply pass through it. Very short wavelengths, such as X-rays, pass through the cell because their energy is too high to be absorbed.
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.
Do color filters affect solar cell voltage output?

However, the short-circuit current is affected by using the color filters. When covered with the yellow filter the cell produces more current than when covered with the red or blue respectively.
How does light affect a photovoltaic cell?
Light causes the charges to move, producing an electric current. Materials containing different impurities change the wavelengths at which the cell responds in different ways. 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.
