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.
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.
St. Petersburg Scientists Propose a Technology That Can Reduce the Cost of High-Efficiency Solar Cells
A group of St. Petersburg scientists has proposed and experimentally tested a technology for the fabrication of high-efficiency solar cells based on A3B5 semiconductors integrated on a silicon substrate, which in the future may increase the efficiency of the existing single-junction photovoltaic converters by 1.5 times. The development of the technology was forecasted by the Nobel Laureate Zhores Alferov. The results have been published in the journal Solar Energy Materials and Solar Cells.
A research group from ITMO University has published a review paper on the prospective use of halide perovskite-based materials, which they believe are capable of causing a revolution in nanophotonics. The paper was spoken highly of by the editorial board of Applied Physics Reviews. In this article, the researchers speak to ITMO.NEWS about the unique qualities of perovskites that will allow them to improve the efficiency of solar cells and describe the advantages of the new material over the conventional silicon.
The names of winners of the Presidential Grant contest have been announced. Among them are four ITMO University scientists. ITMO.NEWS talked to the researchers and learned what projects they are going to spend their grants on.
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.
ITMO students and young scientists took part in the Open Day at The Faculty of Physics and Engineering and shared their experience of studying at the Faculty with applicants.
Scientists from ITMO University have developed a new solar cell coating based on amorphous silicon that combines the features of an electrode and those of a light-trapping structure. The coating enabled researchers to cut down on reflected light and avoid the overheating of solar cells, thus increasing their overall efficiency by 20%. Moreover, the suggested method is highly suitable for industrial needs due to its relatively low cost and simplicity. The research was published in Optics Letters.
