Max p.d of photons across pn junction
Photons with frequency 4.57x10^14Hz are incident on a pn junction in a solar cell. What is the maximum potential difference these photons produce across this junction?
I calculated E to be 3.03x10^19 J but I don't really know where to go from here. I thought maybe E=1/2QV but I don't know how to get charge?
