Colloidal quantum dots make LEDs shine bright in the infrared

(ICFO-The Institute of Photonic Sciences) A group of ICFO researchers report on the development of a colloidal quantum-dot light emitting diode with unprecedented quantum and power conversion efficiencies in the infrared range.The study, published in Nature Nanotechnology, has proven that these devices can also be integrated in inorganic solar cells and may lead to even higher efficiencies
