Q2 Consider a solar cell made of semiconducting nanocrystals with a bandgap energy of Wg = 0.67 eV. Determine the theoretical efficiency when the solar cell is exposed to the radiation of a 6000-K black body? Assume that photons with less than 3.3 Wg create each one single electron/hole pair and that those with more than 3.3 Wg create 2 electron/hole pairs each owing to impact ionization. [50 marks]
