That's the reason for the photoelectric effect that Einstein won the Noble prize in, blue light (u.v. light) has more energy than red (or infra red) light, everything in electricity depends on energy, frequency.Firebenderhttps://www.blogger.com/profile/03005580005084258751noreply@blogger.comtag:blogger.com,1999:blog-4690748651358642939.post-11611227188222011842022-01-22T19:07:22.688+05:302022-01-22T19:07:22.688+05:30as mentioned, the spontaneous single direction dri...as mentioned, the spontaneous single direction driving force (developed by PN junction barrier) is absent in conductors (since electrons move randomly) we need one.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4690748651358642939.post-60223172495606284042017-12-01T19:51:26.019+05:302017-12-01T19:51:26.019+05:30I was also doing a research on PV solar cells and ...I was also doing a research on PV solar cells and this exact question came to my mind and your answer really satisfies me! thank you so much!oridoloreshttps://www.blogger.com/profile/01549175403206390531noreply@blogger.comtag:blogger.com,1999:blog-4690748651358642939.post-44030038333839903522017-10-14T09:42:42.962+05:302017-10-14T09:42:42.962+05:30Why can't we create a pn junction in a conduct...Why can't we create a pn junction in a conductor?Anonymoushttps://www.blogger.com/profile/14839213168994441543noreply@blogger.comtag:blogger.com,1999:blog-4690748651358642939.post-1518134205605657132017-03-15T14:02:52.213+05:302017-03-15T14:02:52.213+05:30Your Explanation given more energy to continue my ...Your Explanation given more energy to continue my work with keen interest.
