An international team of researchers from Russia's ITMO and Tor Vergata University of Rome found a way to increase the efficiency of perovskite-based solar cells. <br />The researchers developed a paste made from titanium dioxide and resonant silicon nanoparticles that serves as an additional layer in the process of producing solar cells. The Mie-resonant particles in the paste make it possible to control the amount of light absorbed and increase the generation of photocurrent, which allowed the researchers to bring the efficiency of solar cells up to 21%.<br /><br />Credit: Ekaterina Shevyreva, ITMO.NEWS<br /><br />Research paper: Mie-resonant mesoporous electron transport layer for highly efficient perovskite solar cells <a href="https://www.sciencedirect.com/science/article/abs/pii/S2211285521007370" target="_blank" rel="nofollow">https://www.sciencedirect.com/science/article/abs/pii/S2211285521007370</a><br /><br />News Source: <a href="https://news.itmo.ru/en/science/photonics/news/12108/" target="_blank" rel="nofollow">https://news.itmo.ru/en/science/photonics/news/12108/</a><br /><br />Playlist for Technology News Videos - <a href="https://www.youtube.com/playlist?list=PLK2ccNIJVPpB_XqWWq_oaZGIDzmKiSkYc" target="_blank" rel="nofollow">https://www.youtube.com/playlist?list=PLK2ccNIJVPpB_XqWWq_oaZGIDzmKiSkYc</a><br />Nano Technology <a href="https://www.youtube.com/playlist?list=PLK2ccNIJVPpBTWAazlaPhTdWJcj0gtcPJ" target="_blank" rel="nofollow">https://www.youtube.com/playlist?list=PLK2ccNIJVPpBTWAazlaPhTdWJcj0gtcPJ</a><br />...<br /><a href="https://www.youtube.com/watch?v=RPEwqqBBnBo" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=RPEwqqBBnBo</a>
