TSCs are emerging devices that combine the advantages of visible transparency and light-to-electricity conversion. One of the valuable prospective applications of such devices is their integration into buildings, vehicles, or portable electronics. Therefore, colour-perception and flexibility are important as well as efficiency. Currently, existing transparent solar cells are based predominantly on organics, dyes, perovskites and amorphous Si; however, the colour-tinted transparent nature or rigidity of those devices strongly limits the utility of the resulting TSCs for real-world applications.
