Researchers at Georgia Institute of Technology has developed a method to stabilize perovskite solar cells using titanium. Silicon, the standard material for solar cells, is costly and energy-intensive to produce, and most of it comes from China. As Perovskite is a cheaper and efficient alternative, degrades quickly, lasting only a year compared to silicon’s 20 years. To improve durability, scientists used vapor-phase infiltration, embedding titanium into the perovskite layer under light vacuum conditions. This process strengthened the material against high temperatures, slowing its degradation. The research team, led by Juan-Pablo Correa-Baena, found that this technique enhances perovskite’s lifespan, making it a viable replacement for silicon. The stabilization method, now under patent review, could help expand domestic solar cell production in the US. The project was funded by the US Department of Energy’s Office of Energy Efficiency and Renewable Energy Solar Energy Technologies Office.
