New Research Could Make Solar 2 to 4 Times Cheaper

Researchers at the University of Michigan have made a discovery that could prevent the rapid degradation of perovskite semiconductors, potentially leading to solar cells two to four times less expensive than current thin-film solar panels. Perovskites, which can be produced at lower temperatures than silicon, degrade when exposed to heat, moisture, and air, limiting their lifespan.

The researchers found that bulky “defect pacifying” molecules, which take up a lot of space, were the most effective at increasing the stability and overall lifespan of perovskite solar cells. This advancement may allow engineers to systematically identify effective molecules for extending the lifespan of perovskite solar cells.
