| Abstract Scope |
Organic-based perovskite semiconductors provide a suitable material candidate to fabricate optoelectronic devices such as solar cells due to its low deposition cost and high efficiency. On the other hand, silicon wafers provide a stable and cost-effective technology for electronics and opto-electronics industries. Combining both materials in photovoltaic solar cells, in what is called Multi-junction (MJ) solar cells, allows the absorbance of a broader range of wavelengths, improving the cell's photo to electrical energy conversion efficiency. Nevertheless, thermal stresses are generated during processing and operation of the perovskite/silicon layer due to the thermal mismatch between both materials. In the current study, different interfaces been explored to reduce intrinsic stresses and therefore decrease defects and therefore enhance stability and increase efficiency of perovskite thin-films. In particular, intermetallic bonding interfaces will be explored which give different results and different stress distribution. The effect of intermetallic bonding will be investigated in this paper. |
