Question

A solar cell generates a potential difference of 0.0788 V when a 500 Ω resistor is connected across it, and a potential difference of 0.1209 V when a 1000 Ω resistor is substituted. What is the internal resistance of the solar cell? Tries 0/10 What is the emf of the solar cell? Tries 0/10 The area of the cell is 5.0 cm2, and the rate per unit area at which it receives energy from light is 2.0m W/ cm2. What is the efficiency of the cell for converting light energy to thermal energy in the 1000 Ω external resistor? (Give answer in %. Do not enter unit)
