c)Because the voltage difference created in the photoelectrode is not able to produce enough voltage to drive the reaction c)1.43V
I=200∗10−9∗1.5∗1092+1000∗10−9∗1.5∗1092=900W/m2
Consider a c-Si solar cell whose fingers have a resistance R=0.1 Ohm. What would be the finger's resistance (in Ohm) if the finger's width is doubled and the finger's height is one third of its initial value?
