Scientists from the National University of Science and Technology, in collaboration with experts from the Institute of Synthetic Polymer Materials of the Russian Academy of Sciences, have succeeded in increasing the heat resistance of perovskite solar cells
Scientists achieved this increase by introducing specialized organic molecules into the material, which improves the stability of its structure.
According to them, the effective operating time of the devices at a high temperature of 80 degrees Celsius increased from 260 to over 700 hours. This is considered a significant step towards creating next-generation solar panels that are both affordable and durable.
"The researchers have enhanced the perovskite's heat resistance by adding triphenylaminepyridine molecules to the material's structure, increasing the devices' effective operating time by almost three times," says Alevtia Chernikova, the university's president. "This proposed method could become fundamental for the wider development of solar panels in the future."
According to experts in the solar panel industry, solar panels with high operating temperatures can be used in hot regions such as deserts, mountainous areas, and in space.
It is worth noting that perovskite materials, compared to silicon, offer higher efficiency in converting light into electricity. Furthermore, they are significantly less expensive and easier to manufacture.
