A solar cell generates a potential difference of 0.320 V when a 445.0 ? resistor is connected across it and a potential difference of 0.504 V when a 945.0 ? resistor is substituted.
A) What is the internal resistance of the cell in Ohms?
B) What is the emf of the cell?
C) The area of the cell is 27.0 cm2 and the rate per unit area at which it receives light energy is 58.0 mW/ cm2. What is the efficiency of the cell for converting light energy to thermal energy in the 945.0 ? external resistor?
