Oxford University scientists have potentially revolutionized access to solar energy by creating an ultra-thin layer of material that can replace bulky silicon-based solar panels. The flexible film, made of stacked perovskite layers just over one micron thick, is 150 times thinner than traditional silicon wafers and can produce 5 percent more energy efficiency. Dr. Shauifeng Hu believes this approach could lead to solar devices exceeding 45 percent efficiency. Not only does this technology reduce construction and installation costs by being applicable to almost any surface, but it also has the potential to increase the number of solar energy farms generating sustainable energy. However, long-term stability of these perovskite panels remains a concern, as they are still in the research stage. The cost of solar energy has dropped significantly over the past decade, making it a more affordable power option. New solar energy farms are emerging globally, including the US Department of Energy converting a former Manhattan Project site into a solar farm and Google investing in a Taiwanese solar company to boost energy production in the region.
