Solved: A solar cell generates a potential difference of
Chapter , Problem 16(choose chapter or problem)
A solar cell generates a potential difference of 0.10 V when a 500 n resistor is connected across it, and a potential difference of 0.15 V when a 1000 n resistor is substituted. What are the (a) internal resistance and (b) emf of the solar cell? (c) The area of the cell is 5.0 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 light energy to thermal energy in the 1000 n external resistor?
