However, the carrier mobility of PbS CQDs is relatively low, which is known to limit device performance [15]. A common approach is to combine PbS CQDs with materials having high carrier mobility to improve device performance [15,16]. ZnO is a direct, wide bandgap (3.37 eV) semiconductor ...
To further improve SnS QDSSC efficiency, the limitations that hinder their large scale commercialization such as secondary phase formation and bulk defects, diffusion length, short minority carrier lifetime, band alignment, solar cell configuration, and back contact should be given important consideration...
