Perovskite Solar Cell
Wladimir_Bulgar @ luchschen
A thin-film technology that couples at least two layers of printed perovskite cells merged into a tandem or a multi-junction solar cell, effectively absorbing light and transporting charge. The printable thin-film cells are made by depositing thin layers of semiconducting film onto plastic, glass, or metal substrate and use 10 to 1000 times less material than crystalline silicon cells.
A perovskite is any material with an ABX3 crystal structure, and currently, different artificial and organic elements such as lead, tin, iodine, bromine, and copper are being tested in inorganic-organic hybrid perovskites for the best cost and efficiency.
Perovskite solar cells are lightweight and flexible, and are set to have a lower cost. Beyond traditional applications such as commercial and residential rooftops and solar farms, perovskite cells could also be applied to cars, high-altitude drones, skyscraper windows, or IoT devices. Current challenges lie in efficiency, stability, and durability.
