An ideal sacrificial layer should thus: 1) present a facile epitaxial growth on perovskite oxide substrates with custom orientation, 2) allow a coherent epitaxial growth of perovskite oxide films, and 3) present a high selectivity toward the liquid etchant. In the following, the main sacrificial layers proposed in the literature and the main transfer methods are reviewed.
To make the desired perovskite material, the initial step involves dissolving all of the precursor material in a solvent. During the second stage, the perovskite material is put onto the substrate in a manner that fully envelops it.
Crystallization of the perovskite material occurs in the third and final stage as the solvent is forced off during the annealing process. It is usual practice to make use of anti-solvents such as toluene, diethyl ether, or chlorobenzene (CB) in order to induce homogeneous nucleation.
The utilization of the remarkable inherent properties of perovskite materials can only be maximized through the use of high quality films. The basic process for creating PSCs involves building up layers of solar cells one on top of another.
In this process, a one-step perovskite precursor solution was made by adding both PbI 2 and MAI in the DMF+DMSO solution with a volume ration of 1:4. The precursor solution was made at one-step, it was directly spin-coated above the substrate at an rpm of 3000 for 50 s.
Improving the stability of perovskites requires careful consideration of various aspects of their systematic engineering, such as structural design, charge transport materials, electrode material preparation, and encapsulation techniques.
