Question

Example use clements such as silicon to fabriceta solar odlls that will generite electricity wpodd to sunlight. Solar cells ure oñea costed with a thin trensparent 6im, such as sillicon monoxide monoxide for thist mimize relective loses. A silicon oel B - 3.5, is coated with s thin 6im of the fgur opdcal bosu of radisns shown, discuss whether each of the reflected beams will bave a phase change due to phase change wlpc boundaries showa. If a phase change is present, determine how large this their relections off of the be units of degrees or radians. Be sure to support your enswers with good physics Beam #1 Si Beam #2 to the reflections present, are the beams in phase or out of phase ? (b) In order to minimize reflective losses, should the two reflected beams add together constructively or destructively? What should be the total phase difference between the two beams to accomplish this ? (c) Determine the minimum thickness of the film that will produce the least amount of reflection for incident sunlight of wavelength 550 nm. Do you think that the transmitted light (beams 3 &4) will be of a maximum intensity or minimum intensity under these conditions? Explain.
