Our findings are essential to engineer and control one of the most promising solar cell materials for optimal utilization. It&#8217;s very exciting that we now have simulation methods that can answer questions that were unresolved just a few years ago,&#8221; says Julia Wiktor, the study&#8217;s principal investigator and an associate professor at Chalmers.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Promising_materials_for_efficient_solar_cells\"><\/span>Promising materials for efficient solar cells<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Materials lying within a group called halide perovskites are considered the most promising for producing cost-effective, flexible and lightweight solar cells and optoelectronic devices such as LED bulbs, as they absorb and emit light extremely efficiently.

It has outstanding optoelectronic properties.<\/p>\n<p>Greater use of the material has been hampered by its instability but this can be solved by mixing two types of halide perovskites. However, more knowledge is needed about the two types so that researchers can best control the mixture.<\/p>\n<p>                                                                                                        <!-- TechX - News - In-article --><\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_key_to_material_design_and_control\"><\/span>The key to material design and control<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A research group at Chalmers can now provide a detailed account of an important phase of the material that has previously been difficult to explain by experiments alone.

This allows them to test the materials by exposing them to different scenarios and these are confirmed experimentally.<\/p>\n<p>Nevertheless, modeling materials in the halide perovskite family is tricky, as capturing and decoding their properties requires powerful supercomputers and long simulation times.<\/p>\n<p>&#8220;By combining our standard methods with machine learning, we&#8217;re now able to run simulations that are thousands of times longer than before. And our models can now contain millions of atoms instead of hundreds, which brings them closer to the real world,&#8221; says Dutta.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Lab_observations_match_the_simulations\"><\/span>Lab observations match the simulations<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The researchers identified the structure of formamidinium lead iodide at low temperatures. They could also see that the formamidinium molecules get stuck in a semi-stable state while the material cools. To ensure that their study models reflect reality, they collaborated with experimental researchers at the University of Birmingham. They cooled the material to\u2014200\u00b0C to ensure their experiments matched the simulations.<\/p>\n<p>&#8220;We hope the insights we&#8217;ve gained from the simulations can contribute to how to model and analyze complex halide perovskite materials in the future,&#8221; says Erik Fransson, at the Department of Physics at Chalmers.<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\tRevealing the Low-Temperature Phase of FAPbI3 Using a Machine-Learned Potential, <i>Journal of the American Chemical Society<\/i> (2025). <a rel=\"nofollow\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1021\/jacs.5c05265\" target=\"_blank\">DOI: 10.1021\/jacs.5c05265<\/a><\/p>\n<\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Chalmers University of Technology<br \/>\n                                                    \t\t\t\t\t\t\t\t\t\t\t\t\t<a rel=\"nofollow\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.chalmers.se\/\" target=\"_blank\" rel=\"nofollow\"><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<use href=\"https:\/\/techx.b-cdn.net\/tmpl\/v2\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/svg><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                <strong>Citation<\/strong>:<br \/>\n                                                Piecing together the puzzle of future solar cell materials (2025, September 24)<br \/>\n                                                retrieved 24 September 2025<br \/>\n                                                from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2025-09-piecing-puzzle-future-solar-cell.html\n                                            <\/p>\n<p>\n                                            This document is subject to copyright.
