Brazilian researchers have actually established a technique to enhance the performance and toughness of perovskite solar cells by incorporating MXenes into the cells structure. For João Pedro Ferreira Assunção, very first author of the article and a masters prospect under UNESPs program of graduate studies in products science and technology, the results were unexpected due to the fact that the initial aim of the job was simply to remediate the drop in efficiency triggered by the addition of the insulating passivation layer.Research on perovskite solar cells is currently focusing on how to design massive commercial production systems to make steady high-performance cells. It also describes numerous electrical, morphological, and structural characterization techniques that we explored to increase the clinical understanding of how this complex class of devices acts and works,” Assunção said.The study is an appealing step toward the sustainability goals of producing clean energy, reducing ecological impact, and making Brazil a leading industrial producer of solar cells, he added.Reference: “Interface passivation with Ti3C2Tx-MXene doped PMMA film for steady and extremely effective inverted perovskite solar cells” by João Pedro F.
