A solar cell of 10cm x 10cm size and with an energy band gap of 1.14 eV has an efficiency η = 15% when it is operating under the standard sunlight condition (AM1.5 solar spectrum and solar power of 1000 W/m2 ). The open circuit voltage Voc of this solar cell is 0.6 V, the short circuit current Isc is 3.5 A, and the voltage at maximum power Vmp is 0.5 V. (a). Find the lowest-frequency photon that can promote an electron from the valence band to the conduction band as well as the wavelength of this photon. (b). What is the maximum power output of this solar cell? (c). What is the current at maximum power?
