The researchers have developed a new class of materials comprising elements such as bismuth, iron, chromium, and oxygen. These\u201cmultiferroic\u201d materials absorb solar radiation and possess unique electrical and magnetic properties. This makes them highly promising for solar technology, and also potentially useful in devices like electronic sensors and flash memory drives. The results of this research are discussed in an&nbsp;<a href=\"http:\/\/www.nature.com\/nphoton\/journal\/vaop\/ncurrent\/full\/nphoton.2014.255.html\" target=\"_blank\" rel=\"noreferrer noopener\">article<\/a>&nbsp;published in&nbsp;<a href=\"http:\/\/www.nature.com\/nphoton\/index.html\" target=\"_blank\" rel=\"noreferrer noopener\"><em>Nature Photonics<\/em><\/a>&nbsp;by researcher and lead author Riad Nechache.<\/strong><\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/dev.inrs.ca\/wp-content\/uploads\/2020\/12\/NEWS_New-materials-for-more-powerful-solar-cells_01.jpg\" alt=\"\" width=\"768\" height=\"462\"\/><\/figure><\/div>\n\n\n\n<p>The INRS research team discovered that by changing the conditions under which a thin film of these materials is applied, the wavelengths of light that are absorbed can be controlled. A triple-layer coating of these materials\u2014barely 200 nanometres thick\u2014captures different wavelengths of light. This coating converts much more light into electricity than previous trials conducted with a single layer of the same material. With a conversion efficiency of 8.1% reported by Nechache and his coauthors, this is a major breakthrough in the field.<\/p>\n\n\n\n<p>The team currentlyenvisions adding this coating to traditional single-crystal silicon solar cells (currently available on the market). They believe it could increase maximum solar efficiency by 18% to 24% while also boosting cell longevity. As this technology draws on a simplified structure and processes, as well as abundant and stable materials, new photovoltaic (PV) cells will be more powerful and cost less. This means that the INRS team\u2019s breakthrough may make it possible to reposition silicon PV cells at the forefront of the highly competitive solar energy market.<\/p>\n\n\n\n<p><strong>About this publication<\/strong><\/p>\n\n\n\n<p>The&nbsp;<a href=\"http:\/\/www.nature.com\/nphoton\/journal\/vaop\/ncurrent\/full\/nphoton.2014.255.html\" target=\"_blank\" rel=\"noreferrer noopener\">article<\/a>&nbsp;published in&nbsp;<em><a href=\"http:\/\/www.nature.com\/nphoton\/index.html\" target=\"_blank\" rel=\"noreferrer noopener\">Nature Photonics&nbsp;<\/a><\/em>is entitled \u201cBandgap tuning of multiferroic oxide solar cells.\u201d The research was conducted at Institut national de la recherche scientifique (<a href=\"https:\/\/dev.inrs.ca\/en\/inrs\/research-centres\/energie-materiaux-telecommunications-research-centre\/\">\u00c9nergie Mat\u00e9riaux T\u00e9l\u00e9communications Research Centre, Varennes<\/a>) by Professor Federico Rosei\u2019s team of researchers made up of Riad Nechache, C.
