The Path to a Brighter FutureSolar energy is on the verge of a breakthrough. Researchers have developed a new method for producing solar cells using perovskite, a next-generation material that could significantly outperform traditional silicon panels. Discuss© Ferra
The efficiency of modern silicon panels is about 22%, that is, they are able to convert only a portion of sunlight into electricity. Perovskite is capable of being much more efficient, potentially reaching 30% or more when combined with silicon in tandem cells. This could significantly increase the amount of electricity produced by solar cells.
Perovskite solar cells have faced challenges in large-scale production due to their sensitivity to oxygen. However, the researchers found a solution: adding a special additive called DMAFo to the perovskite solution prevents it from reacting with air during the coating process. This breakthrough allows products to be manufactured outside of a controlled environment, paving the way for cheaper and faster manufacturing.
Perovskite cells should also be as durable as silicon panels, which can last for decades. While early testing is promising, with DMAFo-treated cells retaining 90% of their efficiency after prolonged exposure to light, longer testing is needed to ensure they can compare to silicon cells, which have a lifespan of 25 years.
