Calculate the total amount of radiative energy per second intercepted by Mars from the Sun using the flux of radiation from the Sun at Mars' orbital radius. Flux of radiation from the Sun at Mars' orbital radius is 597 W m-2. The luminosity of the Sun Ls = 3.8×1026 W. Mars orbits at a distance of 2.25×1011 m (1.5 AU) from the Sun. Note: Consider carefully the cross-sectional area Mars presents to the outwards flow of radiative energy when answering this question.
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?
1 Solar constant, Sun, and the 10 pc distance! The luminosity of Sun is + 4- 1026 W - 4- 1033ergs-1, The Sun is located at a distance of m from the Earth. The Earth receives a radiant flux (above its atmosphere) of F = 1365W m- 2, also known as the solar constant. What would have been the Solar contact if the Sun was at a distance of 10 pc ? 1AU 1 1.5-+ 1011
