Ecole Polytechnique Fédérale de Lausanne (EPFL) researchers have combined silicon and perovskite materials making a tandem solar cell. The resulting efficiency of 25.2 percent is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30 percent. […]

Lawrence Berkeley National Lab (Berkeley Lab) researchers have discovered that a form of perovskite, one of the most studied materials in solar research currently due to its high conversion efficiency. The researchers discovered the perovskite works surprisingly well as a stable and photoactive semiconductor material that can be reversibly switched between a transparent state and […]

Georgia Institute of Technology researchers have devised a new low-temperature solution printing technique allows fabrication of high-efficiency perovskite solar cells. The technique uses large crystals intended to minimize current-robbing grain boundaries. The meniscus-assisted solution printing (MASP) technique boosts power conversion efficiencies to nearly 20 percent by controlling crystal size and orientation. The process, which uses […]

Ulsan National Institute of Science and Technology (UNIST) scientists have introduced a new way to increase energy efficiency of metal-air batteries by substituting platinum with perovskite enhanced by simply adding a kind of conducting polymer, polypyrrole. The breakthrough research, led by Professor Hyun-Kon Song and Professor Guntae Kim of the institute’s department of Energy and […]

Brookhaven National Laboratory scientists have discovered a new phenomenon of perovskite that could have practical applications. Perovskites are expected to have applications in solar cells, rechargeable battery electrodes, and water-splitting devices. When one type of perovskite, known as BSCF for its constituents of barium, strontium, cobalt, and iron, is exposed to both water vapor and […]
