| Outline of Final Research Achievements |
The scientific objective of the proposed work is to develop non-toxic Sn-based environmentally friendly and stable perovskite solar cells (PSCs), where the new proposed hydrophobic robust 2D/3D tin-perovskites layer will play the role of light absorbing materials. In this project, I have designed and prepared 2D/3D dimensionally tuned PS layer. This 2D/3D layer was optimized and successfully integrated as absorbers in a graded heterojunction structure (GHJ) in planar PSCs where heavily doped inorganic charge extraction layers were used. The photovoltaic performances of the PSCs were evaluated by J-V characteristics. 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. The research results are presented at international scientific meetings and also published in more than 10 peer reviewed scientific journals.
