• Scientists Propose a Carbon Dot-Based Method for Increasing the Efficiency of Solar Cells and LED

  An international group of scientists, including some from ITMO University, has proposed a method that allows for significantly increasing the efficiency of solar cells and light-emitting diodes. The scientists managed to achieve this result by augmenting the auxiliary layers of the devices responsible for electron transport rather than working with the main active layer. The work has been published in the journal Advanced Functional Materials.

• It’s All about Carboneum: How Carbon-Based Materials Help Create Efficient and Safe Solar Cells

  Solar cells have already become a symbol of modern technologies and fight for the environment. At the same time, the solar power industry is always on the go: manufacturers strive to improve the efficiency of their devices, and scientists and engineers look for ways to produce solar cells that wouldn’t require highly toxic materials. One of such methods has to do with using nanostructures made of carbon, a safe, affordable and reliable material, for producing solar cells’ supplementary layers. A team of scientists that included researchers from ITMO university has recently published a review on the recent advances in this field. ITMO.NEWS spoke to one of its authors, ITMO’s senior researcher Aleksandr Litvin, and learned how carbon helps make solar cells safer and more efficient.

• ITMO University Professor Joins Nanomaterials as Special Issue's Guest Editor

  Today, physicists, chemists, and materials scientists around the globe seem to have immersed themselves in the world of nanostructures, which promises us materials for unique lasers, remarkably efficient solar cells, quantum computers, and high-resolution monitors. But how efficiently can modern physics explain all the processes taking place in the nanoworld? Do theoretical and experimental physicists have enough reliable and simple tools to solve fundamental problems concerning nanomaterials? These questions are the subject of the special issue of the international peer-reviewed journal Nanomaterials". Its guest editor is Anatoly Fedorov, the head of the International Research and Education Center for Physics of Nanostructures and a professor at ITMO University.

• ITMO Researchers Describe Carbon Dot Structure, Discover Red Emission Amplification Method

  Fluorescent carbon nanoparticles, also known as carbon dots, were first described in the early ‘00s. But even today, scientists around the globe still have not reached a consensus on their inner structure and emission process. Carbon dots have a great deal of potential applications due to their biocompatibility with the human body and the ease and low cost of their production as compared to semiconductor quantum dots. Researchers from ITMO University have published two research papers in which they put forth their answers to the burning questions about carbon dots.

• ITMO Begins Research on Carbon Nanodot Synthesis Methods

  The Russian Government has awarded Professor Andrey Rogach and ITMO University’s International Research and Education Center for Physics of Nanostructures with a “megagrant*” to facilitate the creation of the Laboratory “Light-emitting Carbon Quantum Nanostructures”. There, scientists will study new methods for synthesis of carbon nanodots, which are expected to find use in LEDs and for the purpose of biomedical sensing, i.e. the analysis of chemical substances in living tissue. These new eco-friendly structures will greatly fit into today’s popular “green” nanophotonics concept
