\[  I = I_{ph}-I_0 exp(\frac{q(V-IR_S)}{kT}) + \frac{V-IR_S}{R_{sh}}  \]  where \(I_ph\) is the photo-generated current, \(I_0\) and \{R_{sh}} \(R_{sh}\)  is the shunt resistance of the cell. (sqlimitjap2015). **Figure idea:** Analogous to the 2015 article, create an excess carrier concentration plot for CdTe.
