What is meant by solar spectrum?

The bandwidth of radiant energy—from long wave to short wave. It consists of radio waves, microwaves, visible light (red and violet), ultraviolet rays, X rays, and gamma rays.

What type of spectrum is the solar spectrum?

emission spectrum
The spectrum of the Sun appears as a continuous spectrum and is frequently represented as shown below. This type of spectrum is called an emission spectrum because what you are seeing is the direct radiation emitted by the source.

What are the characteristics of solar spectrum?

Solar spectrum consists mainly, 44.7% of visible radiation (380 ∼ 780 nm), 6.6% of ultraviolet radiation (<380 nm) and 48.7% of infrared radiation (>780 nm)….Related terms:

• Solar Energy.
• Photovoltaics.
• Titanium Dioxide.
• Solar Radiation.
• Solar Cells.
• Photons.

• Photocatalysts.

What is spectrum of solar radiation?

Solar radiation is radiant (electromagnetic) energy from the sun. The three relevant bands, or ranges, along the solar radiation spectrum are ultraviolet, visible (PAR), and infrared. Of the light that reaches Earth’s surface, infrared radiation makes up 49.4% of while visible light provides 42.3% 9.

What kind of spectrum is the solar spectrum?

The Solar Spectrum. . The solar spectrum consists of a continuum with thousands of dark absorption lines superposed. The lines are called the Frauenhofer lines, and the solar spectrum is sometimes called the Frauenhofer spectrum.

What are the dark lines in the solar spectrum?

Spectrum The solar spectrum consists of a continuum with thousands of dark absorption lines superposed. The lines are called the Frauenhofer lines, and the solar spectrum is sometimes called the Frauenhofer spectrum. These lines are produced primarily in the photosphere. The Frauenhofer Spectrum

How does the solar spectrum change with location?

(b) DAS: data logger (CR10X), battery, and computer. The solar spectrum changes throughout the day and with location, making the down-shifter efficiency dependent of the spectral energy distribution [63, 64].

How is the total irradiance of the solar spectrum integrated?

To get the total irradiance in units of W m –2, the spectral irradiance should be integrated over all the wavelengths. Note the following for the solar spectrum: About half of the energy is in the visible wavelengths below 0.7 μm.
