Solar Cell A solar cell generates a potential difference of 0.10 V when a 600 resistor isconnected across it, and a potential difference of 0.15 V when a1150 resistor is substituted.
a) What is the internal resistance?
b) What is the emf of the solar cell?
c) The area of the cell is 5.0cm2, and the rate per unit area at which it receivesenergy from light is 2.0 mW/cm2. What is the efficiencyof the cell for converting the light energy to thermal energy inthe 1150 externalresistor?
