Question

Solar radiation with irradiance of 500 W/m2 is incident upon a solar cell of area 100 cm2. Estimate the number of electron-hole pairs, per second, that lead to the short circuit current of the solar cell if it has 15% efficiency. Assume the photon energy of 2 eV. A. 1.26x1019 pairs/s B. 1.56x1019 pairs/s C. 1.8x1019 pairs/s D. 2.1x1019 pairs/s E. 2.4x1019 pairs/s
