In the graph below, the yellow region shows the AM 1.5 solar spectrum. The area indicated by the blue area represents the AM 1.0 spectrum. The boundaries of the AM 1.0 spectrum;
When λ = between 250nm and 1000nm Pλ = 1x109Wm^(-2) m^(-1)
When λ = between 1000nm and 2000nm Pλ = 0.25x109W m^(-2) m^(-1)
In that case;
a-) Find the radiation intensity (I) and photon flux () for AM 1.0.
b-) If the radiation intensity in the option a comes to the silicon solar cell with a band gap of 1.12eV, how much will the photo-current be produced?
When astronomers look at the spectrum of the Sun, they noticed that the light from one edge is slightly blue-shifted, while light from the opposite age is slightly red-shifted. What does this tell you about the Sun?

- The edge of the Sun doesn’t have to be absolutely sharp in order to look that way to us. It just has to go from being transparent to being completely opaque in a distance that is smaller than your eye can resolve. Remember from Astronomical Instruments that the ability to resolve detail depends on the size of the telescope’s aperture. The pupil of your eye is very small relative to the size of a telescope and therefore is very limited in the amount of detail you can see. In fact, your eye cannot see details that are smaller than 1/30 of the diameter of the Sun (about 1 arcminute). Nearly all the light from the Sun emerges from a layer that is only about 400 km thick. What fraction is this of the diameter of the Sun? How does this compare with the ability of the human eye to resolve detail? Suppose we could see light emerging directly from a layer that was 300,000 km thick. Would the Sun appear to have a sharp edge?arrow_forwardAnswer these questions for celestial bodies at each of the following temperatures and then draw a conclusion about the relationship between temperature and wavelength of maximum intensity.

- If the atmosphere were twice as thick as it currently is (extending farther into space), what effect would this have on the color the sun would appear to be? It would look whiter It would look redder It would have no effect O It would look bluerarrow_forwardSuppose you are working with a photosensitive material that you know is sensitive to green light, but you do not know whether it is sensitive to any other colors. If you must work with the material in some kind of light that you can see, what would be more likely to damage the material, red light of high intensity, or purple light of low intensity?arrow_forwardThe temperature of the sun is approximately 5800 K and the temperature of the star Sirius A, the larger star of the Sirius via art, is approximately 10,000 K. The luminosity of Sirius A is about 33 times than Sun. The radiation law gives L=4(3.14) R^2 a T^4 By taking the ratio of the luminosities of Sirius A to the Sun, the relative values of luminosity and temperature can be used to determine the relative value of radius. What is the multiples of the Sun’s radius?arrow_forward
