Sunlight is the most abundant, safe and clean energy source for sustainably powering economic growth. One of the most efficient and practical ways to harness sunlight as.

Despite the fact that the bandgap is a fundamental material property, there remains.

Owing to thermodynamic factors (equation 2), at temperatures >0 K, it is not possible to convert all the energy associated with a separated electron–hole pair into usable free energy.

A plot of the maximum \({J}_{{\rm{SC}}}^{{\rm{SQ}}}\) versus \({E}_{{\rm{g}}}^{{\rm{PV}}}\) is shown in Fig. 2a. The experimental photocurrents at short circui.

There is an exponential decrease in the density of electronic states from the band edges in semiconductors. Here, we discuss to what extent these tail states influence the voltage out.
