Solar cell generates a potential difference

Reference no: EM13646808

A solar cell generates a potential difference of 0.10 V when a450 resistor is connected across it, and a potential difference of 0.15 V when a1200 resistor is substituted.

(a) What is the internal resistance of the solar cell?
(b) What is the emf of the solar cell?
(c) The area of the cell is 8.0cm², and the rate per unit area at which it receivesenergy from light is 2.0 mW/cm². What is the efficiency of the cell for converting the light energy to thermal energy inthe 1200 external resistor?
