Researchers at the Korea-based Ulsan Institute of Science and Technology (UNIST) have announced the development of a method to produce perovskite solar cells, demonstrating hybrid organic/inorganic perovskite solar cells of 21.2% efficiency, with good stability – retaining 93% of the initial performance after 1,000 hours of light exposure.

The study, a collaboration between UNIST and the Korea Institute of Chemical Technology (KRICT), proposes a new manufacturing method for perovskites - the ‘hot-pressing method’. The University says that this method allows the production of stable, low cost-high efficiency perovskite solar cells.
