QUESTION 9 If a semiconductor with a larger bandgap than Si is used in a single junction photovoltaic cell, which of the following (may be more than one) will be true? The efficiency of the cell will increase. The cell will be less effective at converting IR radiation from the sun to electricity. The semiconductor will not require doping. The cell will be more effective at converting higher energy solar photons (corresponding to its band gap) to electricity. QUESTION 10 The bandgap for a GalnP semiconductor is 1.90 eV. What wavelength of electromagnetic radiation will be used most efficiently (highest fraction of energy from light converted to electrical energy) if this semiconductor were used in a photovoltaic device? (12V= 1.602 x 10-19 J) 1300 nm, IR 670 nm, red light 560 nm. green light 470 nm, blue light 280 nm, UV
