## Solar Power

Suppose a PVC solar cell converts or absorbs 30% of the electromagnetic radiation which falls upon it, where I understand that “Gamma rays” or the such simply pass through it, would it not be so that a large portion of the 70% not converted, if directed to yet another PVC, could this second PVC convert 30% of the reflected 70% which the first PVC did not convert?

I believe the answer is “Yes, for the most part” which would than imply that the unabsorbed portion of the second pass could be directed again to a third PVC.

Is this correct?

## Current Electricity – Combination of Cells

12 cells,each of emf 1.5V and internal resistance, are arranged in ‘m’ rows each containing ‘n’ cells connected in series.calculate the values of ‘n’ and ‘m’ for which this combination would send maximum current through an external resistance of 1.5ohm.
