  • 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.

  • Researchers Use Silicon Nanoparticles for Enhancing Solar Cells Efficiency

    An international research group improved perovskite solar cells efficiency by using materials with better light absorption properties. For the first time, researchers used silicon nanoparticles. Such nanoparticles can trap light of a broad range of wavelengths near the cell active layer. The particles themselves don’t absorb light and don’t interact with other elements of the battery, thus maintaining its stability. The research was published in Advanced Optical Materials.
