Someone please help me out with this problem, I can solve for the current but from there i get stuck...(adsbygoogle = window.adsbygoogle || []).push({});

A solar cell generates a potential difference of 0.10 V when a 600 resistor is connected across it, and a potential difference of 0.15 V when a 1150 resistor is substituted. What are

(a) the internal resistance and

(b) the emf of the solar cell?

(c) The area of the cell is 2.0 cm2, and the rate per unit area at which it receives energy from light is 2.0 mW/cm2. What is the efficiency of the cell for converting the light energy to thermal energy in the 1150 external resistor?
