Jianbo Gao, Assistant Professor in the Department of Chemistry and Affiliated Professor in the Yousef Haj-Ahmad Department of Engineering, is leading the novel research in collaboration with international partners from Brown University, Clemson University, Lawrence Berkeley National Laboratory and National Renewable Energy Laboratory in the U.S.<\/p>\n

The research proposes that perovskite nanocrystalline is a less expensive alternative to silicon for use in photovoltaics, a method of converting solar radiation into electricity.<\/p>\n

\u201cThe average household electricity rate in Canada is around 15 cents per kilowatt-hour,\u201d said Gao. \u201cOur goal with this new material is to achieve less than one penny per kilowatt-hour, which is 15 times less than the cost of the traditional silicon photovoltaics technology.\u201d<\/p>\n

Perovskite nanocrystalline can be easily applied to any surface using a spin-coating method that uniformly deposits a thin film, Gao said.<\/p>\n

\u201cIts simple production and low cost make it highly efficient, accessible and affordable,\u201d he said. \u201cAmidst climate change and worldwide efforts to reduce fossil fuel use, this novel material can contribute to advancing renewable energy alternatives. It could change the future of energy in Canada.\u201d<\/p>\n

Gao\u2019s research, \u201cUltrafast Carrier Drift Transport Dynamics in CsPbI3 Perovskite Nanocrystalline Thin Films<\/a>,\u201d was recently published in ACS Nano<\/em>, an open-access journal published by the American Chemical Society (ACS). The journal is one of the top international forums for the communication of comprehensive articles on nanoscience and nanotechnology research at the interfaces of biology, chemistry, engineering, materials science and physics.<\/p>\n

Recent Biochemistry graduate Jasjit Bains (BSc \u201923) is a contributing author on research published in ACS Nano.<\/p><\/div>\n

Also contributing to the research and article was undergraduate student Jasjit Bains (BSc \u201923), who graduated this past June with an Honours Bachelor of Science in Biochemistry.<\/p>\n

Bains applied his research with Gao to his undergraduate thesis, which examined perovskite crystals as an alternative to silicon in other technologies. While the published research paper investigated using perovskite nanocrystals as a new solar cell alternative in solar panels, Bains\u2019 undergraduate thesis investigated perovskite single crystals as an alternative to traditional silicon-based medical instrumentation techniques, such as X-ray imaging.<\/p>\n

Bains researched different synthetic approaches for the same material.<\/p>\n

\u201cFor the nanocrystals, a hot injection method was used, and the final material produced was a very thin and small crystal structure that is great for easily coating a solar panel,\u201d he said. \u201cThe single crystals are cube-like structures. I investigated 10 different synthetic techniques and at the end of my thesis, I proposed my own original synthetic approach.\u201d<\/p>\n

Over the next several years, Gao will continue his research focus on renewable energy and will work with international partners and his colleagues in Brock\u2019s Engineering Department to apply his research to creating solar cell technology and products.<\/p>\n

\u201cThis is a relatively new research direction in Canada \u2014 very few people are working on this,\u201d he said. \u201cNow that we know the material, we need to transform it to a new practical product that will advance society and ultimately make people\u2019s lives better.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
