It was shown that the efficiency of the cells is reduced in low light conditions, but that cells with a high shunt resistance will perform better in weak light than those with low shunt resistance. Their measurements seem to indicate a drop in solar cell efficiency at irradiance levels below 400–600 W/m 2.
