Quantum Efficiency Exceeds 100 Percent in the Photocurrent Generated in Hybrid Inorganic-Organic Semiconductor
Tiny crystals, known as quantum dots, have enabled an international team to achieve a quantum efficiency exceeding 100 percent in the photocurrent generated in a hybrid inorganic-organic semiconductor. Perovskites are exciting semiconductors for light-harvesting applications and have already shown some impressive performances in solar cells. But improvements in photo-conversion efficiency are necessary to take this ...
