The spectral range of the solar cell is mainly in the visible spectrum, wavelength is 400-1100nm and the central wavelength is about 550nm
The wavelength is related to the frequency, wavelength is inversely proportional to frequency.
The specific formula depends on what wave propagates in what transmission medium. For example, the wavelength of light = speed of light * (1 / frequency)
The speed of light is in meters per second,
The spectrum of different colors has different frequencies.
v=f λ In any case
Where V is the wave velocity and F is the frequency, λ It's the wavelength
The absorption intensity of UV spectrum is related to many factors, such as concentration, sample color, solvent type, etc. Due to the influence of substituents, the maximum absorption wavelength shifts. The wavelength is inversely proportional to the energy difference of the orbital occupied by the electron before and after the transition. Therefore, the factors that can cause the change of energy difference, such as conjugation effect, hyperconjugation effect, steric hindrance effect and solvent effect, can produce red shift or purple shift, but the change of absorption peak caused by the group will not be a simple quantitative superposition relationship.
The maximum wavelength that a gaas based solar cell can absorb is 1100nm.
