A salt referred to as guanidinium thiocyanate can enhance the effectivity and stability of perovskite photo voltaic cells, a brand new class of semiconductor that would make solar energy cheaper and extra {powerful}, in response to researchers at UCL.
In a examine printed within the Journal of the American Chemical Society, the workforce confirmed that guanidinium thiocyanate can sluggish and management the way in which perovskite crystals type throughout fabrication, creating smoother and extra uniform layers. This helps scale back the tiny flaws within the materials that may hinder efficiency and shorten a cell’s lifespan.
Tandem perovskite cells—that’s, two or extra layers of photo voltaic cells stacked on prime of one another—are seen as the way forward for ultra-efficient photo voltaic vitality know-how. That’s as a result of every layer will be tuned to soak up totally different components of the photo voltaic spectrum, which means they will convert extra of that gentle into electrical energy. The brand new examine used blended tin-lead perovskites—sometimes the underside layer of stacked cells.
Corresponding creator Dr. Tom Macdonald (UCL Digital & Electrical Engineering) mentioned, “Our approach provides a straightforward, effective way to enhance perovskite quality during manufacturing, delivering solar cells that are both higher performing and more stable, key requirements for…
