resistant

Perovskita’s solar cells are known for their lightness, managing to develop Ultrafin panels with different applications, such as The candle of a ship. However, the stability of this type of cell meant a challenge for its commercial viability. Now, a group of researchers has managed to extend the useful life of a Perovskita solar cell. Short. Scientists from the University of Surrey They have developed Perovskita solar cells that, by incorporating aluminum oxide nanoparticles, improve both durability and efficiency. Thanks to this finding, cells will be more resistant for large -scale application. The problem to be solved. Here you have to make an important comparison, because the solar cells of the study are of Perovskita that are more efficient and economical than those of silicon, so it has been one of the main objectives of the researchers for their commercial implementation. However, the main challenge was that cells They suffered iodine leakscausing the structure to react chemically reducing its performance. In addition, factors such as humidity, heat and oxygen accelerate this process. The investigation. Surrey’s team, together with the United Kingdom physics laboratory and Sheffield University, He has discovered that when integrating aluminum oxide nanoparticles (Al₂O₃) within the Perovskita layer, iodine can be trapped and prevent it from escaping. This simple but effective approach drastically improves the structural integrity of Perovskita’s solar cells, making them more resistant to weather conditions. The results. Solar cells containing nanoparticles maintained high performance for more than two months (1,530 hours), compared to just 160 hours of Standard Perovskita cells. In this way, the investigation has achieved an increase in the durability of ten times more. The incorporation of these nanoparticles has helped create a more uniform Perovskita structure, which has reduced the defects of the material such as moisture and has improved electrical conductivity. Iodine is not always bad. Unlike this study, iodine can be the result of a solution if the right approach is sought. A study group from the University of Beijing has achieved Integrate iodine into a Perovskita structure. In this approach it has stabilized the material and has avoided the degradation that has historically limited its durability. A great future. In 2009, Perovskita’s solar cells only converted 3% of solar energy into electricity, wasting the remaining 97%. However, Thanks to recent advancesits efficiency has exceeded 25%, increasingly bringing them closer to generalized commercial adoption. This progress highlights the great potential of technology, and with more studies, it is expected to continue increasing, approaching even higher figures and opening new opportunities for solar energy.
