Oxford scientists' new light-absorbing material can turn everyday objects into solar panels

Oxford University scientists may have solved one of the greatest hindrances of expanding access to solar energy. Scientists from the university’s physics department have created an ultra-thin layer of material that can be applied to the exterior of objects with sunlight access in place of bulky silicon-based solar panels. The ultra-thin and flexible film is made by stacking layers of light-absorbing layers of perovskite that are just over one micron thick. The new materials are also 150 times thinner than a traditional silicon wafer and can produce 5 percent more energy efficiency than traditional, single-layer silicon photovoltaics, according to a statement released by Oxford University. Dr. Shauifeng Hu, a postdoctoral fellow at Oxford’s physics department, says he believes “this approach could enable the photovoltaic devices to achieve far greater efficiencies, exceeding 45 percent.” This new approach to solar energy technology could also reduce the cost of solar energy. Due to their thinness and flexibility, they can be applied to almost any surface. This reduces the cost of construction and installation and could increase the number of solar energy farms producing more sustainable energy. This technology, however, is still in the research stage and the university doesn’t mention the long-term stability of the newly designed perovskite panels. Going from 6 to 27 percent solar energy efficiency in five years is an impressive feat but stability has always been limited compared to photovoltaic technology, according to the US Department of Energy. A 2016 study in the science journal Solar Energy Materials and Solar Cells also noted that perovskite can provide “efficient, low-cost energy generation” but it also has “poor stability” due its sensitivity to moisture. Solar energy has also become a cheaper power option just over the last decade. The cost of solar photovoltaic technology has dropped by 90 percent in the last 10 years, according to the Global Change Data Lab. New solar energy farms are popping up all over the world. The US Department of Energy announced earlier this month its turning an 8,000-acre piece of land that once housed parts of the nuclear weapons program known as the Manhattan Project into a solar farm. Last month, Google invested in a Taiwanese solar company to build a 1 gigawatt pipeline in the region.This article originally appeared on Engadget at https://www.engadget.com/science/oxford-scientists-new-light-absorbing-material-can-turn-everyday-objects-into-solar-panels-200410760.html?src=rss
