Piece of P type semiconductor is uniformly doped with acceptance concentration NA and is of length W. There are contacts at the two ends, x=0,W. The contact at x=0 is transparent. Light falls on the contact at x=0 creating electron-hole pairs at a rate GL(x)=GL,0 exp(-x/λ), λ =/= L0. Calculate the steady-state excess electron concentration.
