| Outline of Annual Research Achievements |
The scientific objective of the proposed work is to develop non-toxic Sn-based environmentally friendly and stable photovoltaic devices, where the new proposed hydrophobic robust 2D/3D tin-perovskites layer will play the role of light absorbing materials. The prepared 2D/3D dimensionally tuned PS layer was optimized and successfully integrated as absorbers in a graded heterojunction structure (GHJ) in planar PSCs where heavily doped inorganic charge extraction layers of NiMgLiO and Ti(Nb)Ox were used. The photovoltaic performances of the PSCs were evaluated by J-V) characteristics, external quantum efficiency (EQE). The long-term stability of these devices were also studies. Finally, we have successfully fabricated a stable GHJ planar PSCs using 2D/3D dimensional PS films.
