Perovskite is a new material that has become an alternative to silicon in solar energy. It is cheaper, thinner, easier to manufacture, and collects sunlight more efficiently. Speaking to socialbites.ca, Danila Saranin, head of the NUST MISIS advanced solar energy laboratory, said that in the future it will be possible to produce roll solar panels from it.
Due to the iodine content in their composition, such solar panels absorb light approximately 10 times stronger than silicon.
“This means that in an ultra-thin film half a micron thick, we can generate the same amount of energy from sunlight as a 200 micron thick silicon wafer. At the same time, perovskite is 400 times thinner, which allows us to go to the next level and make such films on a flexible substrate.” “In other words, we will have ultra-cheap, flexible, roll-type solar cells in the future. We are also developing these, but such studies are not a priority for now,” he said.
Additionally, such films can be printed using a method similar to the operation of an inkjet printer. This is a big plus compared to silicon batteries, which require ultrapure silicon, vacuum chambers, and a very difficult deposition process onto a substrate. But printing still requires special equipment.
After printing, such films are placed on top of each other. Several layers of perovskite effectively absorb light and convert it into energy.
“Scientists have been trying to find an alternative to silicone since the 80s of the last century. And only now solar energy can more or less compete with fuel and nuclear energy in some areas. The transition to a new technology, such as perovskites with the same high efficiency, promises to significantly reduce costs due to the use of cheap materials and a simplified printing cycle. Manufacturing single-crystal silicon and printing perovskite film are incomparable in terms of cost; The price of perovskite is 2.4 times less than the price of silicon,” Saranin explained.
Previous scientists said We explained how perovskite panels are designed and why they are better than silicon.
