Swiss researchers found a way to build a sustainable, eco-friendly future that doesn’t require a lot of financial resources. They discovered that fully printable and low cost solar cells can provide the same efficiency that solar panels do nowadays, for an extensive period of 10,000 hours #todaymagic
A team of scientists from Switzerland studied perovskites as materials for economic, efficient and durable solar cells. A pervoskite is a type of mineral endowed with superconductivity, magneto resistance and ionic conductivity. It’s capable of making cells that have a higher efficiency than anything else you’ve seen on the market. We’re talking about 31% energy efficiency!
Unfortunately, this remained a hypothesis until now, because the material was always very susceptible to moisture and oxygen. Scientists, though, made a new type of perovskite cell structure that proved stable enough to function over one year, that’s about 10,000 hours. The 10×10 solar panel used a 2D/3D perovskite combo to protect against moisture while generating electricity.
While they didn’t get the maximum efficiency, they did obtain a 11.2% efficiency which is roughly the same you’d get from a silicon-based solar panel. Only this cell is printable, so much more economic than other versions.
Granted, it’s an intermediary step towards a greater goal. The team is optimistic that by tweaking the internal structure of the panel, they will eventually take advantage of the total, theoretical efficiency of the pervoskites.
