Herein, we report unique features of the assemblies tetrapod-shaped colloidal nanocrystals (TpNCs) with lengthy arms applicable to flexible thin-film transistors. Due extended nature tetrapod geometry, films made TpNC require reduced numbers inter-NC hopping for transport charge carriers along a given channel length; thus, enhanced conductivity can be achieved compared those typical spherical NCs without arms. Moreover, electrical conduction through is tolerant against mechanical bending...
We demonstrate the improvement in efficiency of planar heterojunction perovskite solar cells by employing cadmium selenide tetrapods (CdSe TPs) as an electron extraction layer. The insertion CdSe TP layer between titanium oxide (TiO2) and film facilitates transfer at TiO2/perovskite interface, indicated significantly quenched steady-state photoluminescence film. Furthermore, we observed a conductivity enhancement introducing combination both effects induced TPs leads to carrier well...
