A group of researchers have developed a next-generation, more economical perovskite-based solar battery, thereby creating the world’s most efficient solar cell. Led by Professor Seok Sang-il of Sungkyunkwan University (SKKU), the team announced on January 9 that they have successfully developed a new perovskite solar cell technology. The newly developed solar cells are priced at one third the price of existing silicon solar cells and show an efficiency performance rate of 20.1 percent, equivalent to existing silicon solar cells.

This is now the most efficient solar cell officially recognized by the U.S.-based National Renewable Energy Laboratory (NREL).

Currently, silicon solar cells account for about 90 percent of the solar cell market. Silicon solar cells are made from high-purity silicon. They are highly efficient at transforming solar energy into electric energy. Their weaknesses, however, is their complicated production process and expensive price.
