Halide Perovskite Solar Cells Would Improve Solar Energy Technology
Perovskite solar cells, the most promising new technology in industry and academic community has potential as a highly competing substitute to silicon solar cells and other commercial alternatives. New research explains why the Halide perovskite solar cells function in the first place as not many people understood the process and the reason behind it.
Aram Amassian, a co-corresponding author of the study on the work and an associate professor of materials science and engineering at North Carolina State University, said that it is all about the material design. If one wants to purposefully create halide perovskite solar cells that have the useful features one looks for, one must understand how the material acts under various conditions, and why.
Halide perovskites are in essence salts, with positively and negatively charged elements that combine to shape a neutral compound. And they have a few features that make them desirable for producing high-quality solar cells. They can be disintegrated into a liquid and then design high-quality crystals at low temperatures, which is appealing from a manufacturing point of view.

Aside from that, they are not difficult to repair and can accept defects in the material without lowering the performance of their semiconductor properties.
An international team decided to study the critical aspect regarding the halide perovskites solar cell fusion and process. It concerns the fact that adding cesium and rubidium into the fusion process of combined halide perovskites fragments makes the emerging solar cell more chemically homogeneous, which is wanted since this makes the material’s features more consistent all over the cell. Until now, no one knew this.
To examine the issue, the scientists used time-resolved, X-ray prognostics to image and track changes in the crystalline fragments formed all over the synthesis process. The calculations were performed at the Cornell High Energy Synchrotron Source. The next phase includes translating this information from laboratory-based centrifugal to broader area manufacturing platform, which will allow the high amount of material fabrication of perovskite solar cells.
