Additionally, the openings in the consumption can immediately go to the p-type side of the intersection. Once, the recently made free electrons go to the n-type side, can't further cross the intersection due to boundary capability of the intersection.
construction of solar cell? At the point when light arrives at the p-n intersection, the light photons can without much of a stretch enter in the intersection, through exceptionally slight p-type layer. The light energy, as photons, supplies adequate energy to the intersection to make various electron-opening sets. The occurrence light breaks the warm harmony state of the intersection. The free electrons in the consumption area can immediately go to the n-type side of the intersection.
