The problem, which limits the use of these devices in everyday life, has challenged researchers in the field to find viable solutions.<\/p>\n<p>Perovskite solar cells are a very promising photovoltaic <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>. They are as efficient as silicon cells and have lower production costs. In addition, they are light, flexible and semi-transparent, which opens up numerous possibilities for <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lications such as windows, clothing or tents that can generate electricity from sunlight.<\/p>\n<p>However, the commercialization of these cells is hampered by their low durability due to the degradation that perovskite materials undergo when exposed to humidity and ambient temperature conditions during both manufacturing and use. This degradation affects the performance of the devices over time and therefore their durability.<\/p>\n<p>In an article <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0927024825001230?via%3Dihub\" target=\"_blank\">published<\/a> in the journal <i>Solar Energy Materials and Solar Cells<\/i>, the UFABC team describes a process that is unique in that it can be carried out without the strict humidity and temperature controls that exist in laboratories dedicated to researching these devices.<\/p>\n<p>&#8220;The solar cells in this work were obtained under ambient conditions, without major humidity controls, which may be more compatible with industrial preparation conditions,&#8221; explains Professor Andr\u00e9 Sarto Polo, coordinator of the study and member of the Center for Innovation on New Energies (CINE).<\/p>\n<p>                                                                                                        <!-- TechX - News - In-article --><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Modulating_the_composition\"><\/span>Modulating the composition<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The perovskite family includes materials with different chemical compositions. They all share a common structure of positively charged ions (cations) and negatively charged ions (anions). Perovskites based on methylammonium (MA<sup>+<\/sup>) and formamidinium (FA<sup>+<\/sup>) cations are the most studied for use in solar cells.<\/p>\n<p>In this new study, the authors incorporated increasing amounts of formamidinium cations into methylammonium-based perovskites, characterized each of the materials obtained and assembled solar cells with them. The production and characterization of the materials and devices were carried out in environments with relative humidity ranging from 40% to 60%.<\/p>\n<p>To test their stability, these solar cells were exposed to ambient temperature and humidity for 90 days. During this period, the researchers systematically studied the properties of all the devices in order to determine the influence of the addition of formamidinium on the performance of the solar cells.<\/p>\n<p>While solar cells without FA<sup>+<\/sup> showed a sharp drop in efficiency im<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>tely after assembly and stopped working after 30 days, cells with more than 25% FA<sup>+<\/sup> maintained 80% efficiency at the end of 90 days.<\/p>\n<p>&#8220;This work demonstrates how the incorporation of FA<sup>+<\/sup> cations into MA<sup>+<\/sup>-based perovskites causes an increase in the durability of perovskite solar cells fabricated and measured under ambient conditions,&#8221; summarizes Polo.<\/p>\n<p>According to him, this is because the addition of formamidinium causes an increase in the size of the grains that make up the crystalline structure of the perovskite, reducing the overall length of the edges. Since the edges are points where moisture accumulates, the perovskite suffers less degradation and the solar cell maintains its good performance for longer.<\/p>\n<p>The research, conducted during Lucas Polimante&#8217;s doctoral studies, opens up the prospect of developing more durable perovskite solar cells that can be produced at lower cost and in more environmentally friendly conditions.<\/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\tLucas Polimante et al, Enhancing the stability of methylammonium-based perovskite solar cells prepared in ambient conditions by adding formamidinium cations, <i>Solar Energy Materials and Solar Cells<\/i> (2025). <a rel=\"nofollow\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1016\/j.solmat.2025.113522\" target=\"_blank\">DOI: 10.1016\/j.solmat.2025.113522<\/a><\/p>\n<\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                <strong>Citation<\/strong>:<br \/>\n                                                Simple process extends lifetime of perovskite solar cells (2025, May 20)<br \/>\n                                                retrieved 20 May 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>\/2025-05-simple-lifetime-perovskite-solar-cells.html\n                                            <\/p>\n<p>\n                                            This document is subject to copyright.
