Pavel Tonkaev started his Master’s at ITMO University in 2017 after graduating from Peter the Great St. Petersburg Polytechnic University (SPbPU). Since his second year here, Pavel has been studying perovskite materials in nanophotonics and optoelectronics. Current studies suggest that these materials may not only become the future of solar energy but also set the stage for various other technologies, from the creation of sensitive photodetectors to the study of living cells. In this article, Pavel talks about how to get into research in the second year of your Bachelor's, how his discoveries can help people in the future, and why scientists shouldn’t stick to one perspective.
An international team of researchers from ITMO’s School of Physics and Engineering and Tor Vergata University of Rome found a way to increase the efficiency of perovskite-based solar cells. The project was supported by a Russian Science Foundation grant and its results were described in a paper published in Nano Energy.
For today’s International Chess Day, a research team from ITMO’s School of Physics and Engineering presents a unique device – a chess set with light-emitting pieces that contain perovskite. The energy is delivered wirelessly into each piece using a special transmitter embedded into the chessboard.
A research team that includes staff members of ITMO University has suggested a new method of processing miniature perovskite fragments. The method is cheap and makes it possible to fashion microcrystals into desired shapes for use in production of lenses and other optoelectronic elements. This will help bring about the material’s widespread adoption within the industry. A paper on the research was published in Laser & Photonics Reviews.
ITMO scientists grow perovskite crystals and apply functional layers on various materials. In the image, you can see perovskite crystals grown inside textile. Such fabrics can be applied in workwear, decoration, and contemporary art.
Perovskite-based devices could potentially be used to create commercial-purpose full-color displays that would be cheaper and more efficient than their existing OLED counterparts.
Well, it’s actually a demonstration of light distribution in waveguides with an active medium.
The PhD student was recognized for his works on perovskite nanophotonics. In total, four Russian PhD students and six young Russian scientists were awarded the scholarship. Alexander Berestennikov spoke with ITMO.NEWS about this achievement, his research, and why he loves being a scientist.
An international team of researchers announced the development of the world’s most compact semiconductor laser that works in the visible range at room temperature. According to the authors of the research, the laser is a nanoparticle of only 310 nanometers in size (which is 3,000 times less than a millimeter) that can produce green coherent light at room temperature. The research article was published in ACS Nano.
Scientists Develop Light-emitting Composite Material Based on Perovskite Nanocrystals with Air- and Water Resistant Optical Characteristics
An international team of scientists including researchers from ITMO University has developed a new composite material based on perovskite nanocrystals to fabricate miniature light sources with improved performance. Protection of perovskite nanocrystals within porous glass microspheres made it possible to increase their stability by almost 3 times. Moreover, the subsequent coating of these particles with polymers resulted in the fabrication of water-dispersible luminescent microspheres based on CsPbBr3 nanocrystals. This method of fabrication is especially important for the implementation of perovskite nanocrystals in diverse biological applications. The results have been published in ChemNanoMat.
