Question

d) In the up-convertor 1, two photons are converted into one photon with 100% conversion efficiency. If all photons with energy above that of the band gap of a-SiC:H are absorbed in the a-SiC:H layer, in which spectral range can the photons be up-converted so that they contribute to the current in the cell as well?

1)A
2)B
3)C


e) In that case what would be the short-circuit current density and the efficiency of the solar cell illustrated in Figure 2b? Assume again that 65% of the absorbed photons result in a current.

Short-circuit current density in mA/cm2

Efficiency in %

Can someone please solve this asap
