Despite this progress, challenges such as poor long-term stability, phase degradation under light, heat, and moisture, and the toxicity of lead (Pb) remain significant obstacles to commercial scalability and environmental safety.<\/p>\n<p>To overcome these limitations, my research team at the Autonomous University of Quer\u00e9taro, Mexico, focused on chalcogenide perovskites, particularly SrHfSe<sub>3<\/sub>, which exhibits compelling attributes for next-generation solar <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>. This material offers superior chemical stability, a tunable bandgap, a high photon absorption coefficient, and enhanced p-type carrier mobility, making it an excellent candidate for photovoltaic <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.<\/p>\n<p>We investigated SrHfSe<sub>3<\/sub>-based chalcogenide perovskite solar cells within the device architecture FTO\/BaSnO<sub>3<\/sub>\/SrHfSe<sub>3<\/sub>\/HTL\/Au, initially using MoS<sub>2<\/sub>, as the hole transport layer (HTL). We then systematically replaced MoS<sub>2<\/sub> with 40 different HTLs, including inorganic semiconductors, polymers, and MXenes, a novel exploration carried out for the first time by my group.<\/p>\n<p>Using the SCAPS-1D simulation tool, developed by Mark Burgelman, University of Ghent, we conducted a theoretical study, simulating 1,627 device configurations. This allowed us to optimize critical parameters such as absorber acceptor density, defect density, thickness and back contact work functions, all under near-realistic conditions.<\/p>\n<p>Our findings, <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/linkinghub.elsevier.com\/retrieve\/pii\/S0927024825003289\" target=\"_blank\">published<\/a> in <i>Solar Energy Materials and Solar Cells<\/i>, demonstrate that through meticulous device engineering, SrHfSe<sub>3<\/sub>-based chalcogenide perovskites can achieve significant performance gains. The results indicate a promising path toward efficient, stable, and lead-free solar cells. Optimizations led to improved light absorption, minimized recombination losses, enhanced built-in potential, and better charge transport characteristics. Notably, enhanced band alignment and interfacial properties contributed to substantial PCE improvements.<\/p>\n<p>                                                                                                        <!-- TechX - News - In-article --><\/p>\n<p>We analyzed 41 HTLs across 1,627 solar cell configurations, categorizing them into three HTL categories. We then conducted a comparative analysis of these three types by examining the low and high-efficiency HTLs within each group using various techniques, such as capacitance-voltage (C-V), Mott-Schottky analysis, impedance spectroscopy, quantum efficiency studies, and energy band alignments.<\/p>\n<p>Performance enhancements were primarily attributed to higher short-circuit current densities (J<sub>SC<\/sub>), increased quasi-Fermi level splitting, improved carrier generation, stronger internal electric fields, enhanced QE, and diffusion lengths. Among the simulated configurations, the best configuration devices used SnS, CPE-K, and Ti<sub>2<\/sub>CO<sub>2<\/sub> as HTMs, achieving PCEs of 27.87%, 27.39%, and 26.30%, respectively.<\/p>\n<p>This research marks a promising step forward in the search for safer, high-performance alternatives to conventional perovskites. By integrating SrHfSe<sub>3<\/sub> with HTLs, the team has laid a strong foundation for developing stable, efficient, and non-toxic solar cells. As the world moves toward cleaner energy solutions, innovations like this have the potential to reshape the future of photovoltaics.<\/p>\n<p><i>This story is part of <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/sciencex.com\/news\/dialog\/\" target=\"_blank\">Science X Dialog<\/a>, where researchers can report findings from their published research articles. <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/sciencex.com\/help\/dialog\/\" target=\"_blank\">Visit this page<\/a> for information about <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a> X Dialog and how to participate.<\/i><\/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\tDhineshkumar Srinivasan et al, A new class of SrHfSe<sub>3<\/sub> chalcogenide perovskite solar cells with diverse HTMs: Theoretical modelling towards efficiency enhancement, <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.2025.113727\" target=\"_blank\">DOI: 10.1016\/j.solmat.2025.113727<\/a>\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Bio\"><\/span>Bio:<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Dr. Latha Marasamy is a Research Professor at the Faculty of Chemistry-Energy Science Program at UAQ, where she leads a dynamic team of international students and researchers.
