… We further suggest that given the variability of band gaps observed in TMD monolayers, usually in the 1.5?2.5 eV range and decreasing for increasing sizes of the chalcogen atom, significant band gap engineering is possible using stacked TMD bilayers and multilayers. This scenario entails novel possibilities to form broadband sunlight absorbers and enhance efficiency considerably beyond the values estimated here. …
