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.

Academic Significance and Societal Importance of the Research Achievements |
The research results elucidate the future directions of non-toxic environment friendly perovskite solar cells (PSCs) with the challenges of how to further improve the efficiency of toxic lead free PSCs to accelerate the progress in the commercialization of PSCs.
