					</table><p>Researchers at the Indian Institute of Technology (<a href="https://www.iitbhilai.ac.in/" target="_blank" rel="noopener">IIT Bhilai</a>) have developed an innovative self-healing polymeric coating material for photovoltaic applications, which demonstrates the ability to heal cracks spontaneously and offers an accessible and cost-effective solution for self-healing coating materials.</p>
<p>The researchers said the self-healing coating is designed to repair cracks within solar cells in only five minutes.</p>
<p>The self-healing coat material is a polymer called PSt-b-PTEVE, synthesized through a &#8220;water tolerant&#8221; method known as cationic polymerization. This polymer has the remarkable ability to heal cracks independently, owing to its redox responsiveness, and shows promise for various applications, including as a functional coating.</p>
<p>The ability to self-heal is a widely sought-after characteristic that aims to prolong the lifespan of materials due to the inherent susceptibility of all substances to degradation over time.</p>
<p>To achieve this healing capability at both microscopic and nanoscopic levels, intentional design and development of self-healing materials are necessary.</p>
<p>The study, led by Sanjib Banerjee from the Department of Chemistry, was published in the <em>European Polymer Journal</em>.</p>
<p>The researchers noted that the primary motivation behind this research is solar cells&#8217; critical role in combating climate change by harnessing sunlight to generate electricity without consuming fuel or producing harmful emissions.</p>
<p>However, prolonged exposure to hot and humid environmental conditions can inflict damage on solar cells, hampering their efficiency and performance.</p>
<p>The introduction of self-healing coating material is expected to be a game-changer, as it can prevent crack propagation and system failures, effectively restoring the material and system properties, the researchers said.</p>
<p>Nature offers some fascinating examples of self-healing phenomena, but incorporating them into engineered materials for practical applications comes with significant challenges. Banerjee&#8217;s team is dedicated to bridging this gap between natural healing and advanced materials technology.</p>
<p>The simplicity of the coating&#8217;s formulation is another major advantage.</p>
<p>The cost-effectiveness and industry-friendly nature of the process bode well for its eventual integration into solar cell manufacturing.</p>
<p>The venture holds the promise of enhancing the reliability and performance of aerospace technology, making it more resilient to environmental stressors.</p>
<p>Recently, researchers at the Indian Institute of Technology Mandi (IIT Mandi) <a href="https://www.mercomindia.com/iit-mandi-solar-cell-metal-oxide-layers" target="_blank" rel="noopener">claimed</a> a breakthrough in producing metal oxide layers for use in advanced architecture silicon solar cells using a cost-effective method.</p>
<p>Scientists at the National Centre for Photovoltaic Research and Education of the Indian Institute of Technology Bombay (IIT Bombay) <a href="https://www.mercomindia.com/iit-26-efficiency-perovskite-silicon-solar-cell" target="_blank" rel="noopener">claimed</a> to have achieved a power conversion efficiency of more than 26% for a 4 terminal (4T)-silicon perovskite tandem solar cell.</p>
