Question #2 In this problem, you will estimate efficiency limits for solar cells as a function oftheir band gap energy. a) The short-circuit current density (Jsc) of a solar cell can be calculated from the measured external quantum efficiency EQE() using the expression JSC : ICU") IAMX(8) EQE(8) d8 Note: where IAMxle) is the spectral irradiance incident upon the cell under AMO {with x=0) or AM1.5d {with x=1.5d), e is the incident photon energy, and A is the band gap of the semiconductor. 0 Find the functional form of C in the integral given above that will make the above integral true. (Hint: unit analysis will, again, be helpful)
