Tin dioxide (SnO 2) is generally regarded as a promising electron-transporting layer (ETL) for state-of-the-art perovskite solar cells (PSCs), however, the ubiquitous oxygen-vacancy-related defects at SnO 2 surface and the large energy difference between conduction band of SnO 2 and perovskite layer undoubtedly cause severe charge carrier recombination, resulting in sluggish

Recently, graphene-based thin film has attracted extensive interest as absorbers in solar-driven interfacial evaporation systems [, , ].Whereas, pure graphene cannot be used directly for its poor optical absorption property .Reduced graphene oxide (RGO) was introduced relatively well to alleviate this defect [18, 19].Wang et al. integrated a paper-based
Features of the oven are the strong heat resisting (often called pyrex) glass formed into a double walled tube. Within the double wall is a vacuum to provide the best insulation possible, with the heat saving properties of a thermos type flask. The inner wall of the glass tube has a sunlight absorbing layer (on the outer face) to pick up the sun.
