Researchers found that the tiny defects which limit the efficiency of perovskites - cheaper alternative materials for solar cells - are also responsible for structural changes in the material that lead to degradation.
The materials that facilitate this reaction cost a mere $2 per kilogram, and a single kilogram can produce more than 6 liters of water per day in areas with less than 15% relative humidity and 13 liters in areas with up to 30% relative humidity.
