New Generation Silicon Solar Cells

3.5 Generation and recombination

New Generation Silicon Solar Cells

n0 n0 + ∆n = n

Recombination and generation processes. Generation processes depend on absorption and on flow of photons

           G = R   

Life time of minority carriers:

∆n   is the surplus concentration

Ri    is the rate of recombination

n0    is the concentration at equilibrium

n     is the charge concentration

G    is the rate of generation
