Abstract:
We present an efficiency potential analysis of passivated emitter and rear cells (PERC) and passivated emitter and rear totally diffused (PERT) cells, based on numerical simulations covering a wide range of parameters using a state-of-the-art design of experiment and metamodeling approach. We make full use of the metamodel and optimize the rear contact distance in each simulation by defining it as a free variable. PERT solar cells are simulated respecting free carrier absorption at the boron doped back surface field (BSF). As a result, PERC cells show the highest overall efficiency at a low base resistivity of ρb = 0.5 Ωcm, whereas for ρb > 1.5 Ωcm PERT cells exceed the efficiency of the respective PERC cells.
