Perovskite solar cells (PSCs) are among the most promising photovoltaic techniques. They perfectively combine the advantages of high efficiency and very low fabrication cost, which are essential for future territorial employment. However, at present, the low stability of the PSCs toward thermal or moisture treatment severely hinders their practical application. In this talk, we introduce our recent progress in this issue:（1）New type of HTMs free of additive are very beneficial to achieving highly stable PSC device; (2) when the organic HTMs were replaced by inorganic oxides in the graded configuration, very excellent device stability along with superior device performance was realized.  (3) new structured one-dimensional oxides nanoarrays have been exploited as excellent ETMs to experimentally demonstrate the advantage of these materials as high-speed way for carrier transport of PSCs. (4) the high crystallized SnO2 NCs have been encapsulated by amorphous NbOx to form core-shell structured SnO2@NbO<sub>X</sub> NCs， which work as excellent ETMs of PSCs to boost their efficiency ≥24%.
