Spray-on solar cells could be the next big thing for sustainable energy

The two spray heads of the machinery used to spray-paint perovskite solar cellsGenerating solar power can be expensive and impractical for the average person, but a new spray-painting method that applies solar cells to almost any surface could be the next big thing in green energy. Scientists at the University of Sheffield in the UK have developed perovskite solar cells using a spray-painting process, which could turn a variety objects into energy generators. While most solar cells are manufactured using energy-intensive materials like silicon, perovskites requires much less energy to make. By replacing the key light-absorbing layer found in organic solar cells with a spray-painted perovskite, energy efficiency is vastly increased.
