					</table><p>Researchers at the National University of Singapore (<a href="https://nus.edu.sg/" target="_blank" rel="noopener">NUS</a>) have attained a record efficiency of 24.35% in an inverted-structure perovskite solar cell which marks the first time such a high efficiency has been achieved in a perovskite solar cell with a 1 cm2 active area.</p>
<p>The notable success can be primarily attributed to the incorporation of an inventive charge-transporting material within the cells.</p>
<p>The team said the achievement sets a new benchmark for the efficiency of perovskite solar cells and offers promising prospects for cheaper, more efficient, and durable solar energy solutions.</p>
<p><strong>Closing the Efficiency Gap</strong></p>
<p>Led by Assistant Professor Hou Yi, a team of researchers from NUS focused on bridging the efficiency gap and unlocking the full potential of larger-sized perovskite solar cell devices.</p>
<p>The achievement was made possible by successfully incorporating an undisclosed novel interface material into perovskite solar cells, which enabled the cells to achieve higher efficiency than the normal-structured perovskite cells.</p>
<p>Researchers said this interface material possesses optical, electrical, and chemical properties that synergistically enhance the efficiency and longevity of perovskite solar cells.</p>
<p>The introduction of this material paved the way for significant improvements in performance and durability, making perovskite solar cells more commercially viable.</p>
<p>To ensure the long-term viability of perovskite solar cells, the team is actively working on improving their stability. Perovskite materials are sensitive to moisture and can degrade over time.</p>
<p>Developing a customized aging methodology is a key focus to bringing this technology from outside the lab, with the goal of achieving 25 years of operational stability.</p>
<p>Additionally, the researchers are working on scaling the solar cells to modules by expanding their dimensions and demonstrating their effectiveness on a larger scale.</p>
<p>In a similar research, scientists from King Abdullah University of Science and Technology <a href="https://www.mercomindia.com/efficiency-perovskite-silicon-tandem-solar-cells" target="_blank" rel="noopener">combined</a> perovskite top cells on industrially compatible, two-sided, textured silicon bottom cells and developed a perovskite-silicon tandem solar cell with a conversion efficiency of 33.2%.</p>
<p>Experts from North Carolina State University said in an experiment that <a href="https://www.mercomindia.com/channeling-ions-pathways-boosts-perovskites" target="_blank" rel="noopener">channeling</a> ions into defined pathways in perovskite materials improves perovskite solar cells’ stability and operational performance.</p>
