Laser deposition of resonant silicon nanoparticles on perovskite for photoluminescence enhancement

Abstract: Hybrid lead halide perovskite based optoelectronics is a promising area of modern technologies yielding excellent characteristics of light emitting diodes and lasers as well as high efficiencies of photovoltaic devices. However, the efficiency of perovskite based devices hold a potential of further improvement. Here we demonstrate high photoluminescence efficiency of perovskites thin films via deposition of resonant silicon nanoparticles on their surface. The deposited nanoparticles have a number of advances over their plasmonic counterparts, which were applied in previous studies. We show experimentally the increase of photoluminescence of perovskite film with the silicon nanoparticles by 150 % as compared to the film without the nanoparticles. The results are supported by numerical calculations. Our results pave the way to high throughput implementation of low loss resonant nanoparticles in order to create highly effective perovskite based optoelectronic devices.

Resonant silicon nanoparticles for efficiency and stability enhancement of perovskite solar cells

Abstract: A lot of attempts were given to improve efficiency of lead halide perovskites solar cells in last several years by chemically active plasmonic nanoparticles implementation, but there is no data about stability in time. To solve both problem we added low-loss and chemically inert resonant silicon nanoparticles between electron transport layer and perovskite layer that allows to increase not only efficiency enhancement via improved light harvesting, photocurrent, open-circuit voltage and fill-factor, but also we increase these characteristics in few days after device preparation. Silicon nanoparticles allow achieve the device efficiency up to 18.8%, being a record among the previously reported results on nanoparticles incorporation into CH3NH3PbI3 (MAPbk3) perovskite-based solar cells. The proposed method of efficiency enhancement can be used for solar cells with various chemical compositions of perovskites.

Room Temperature Operation of Directly Patterned Perovskite Distributed Feedback Light Source under Continuous-Wave Optical Pumping

Abstract: We report the first directly patterned perovskite distributed feedback (DFB) resonator with a narrow amplified spontaneous emission (ASE) at pump powers as low as 0.1W/cm2, under continuous-wave (CW) optical pumping condition at room temperature.

Electric Field Effect in Atomically Thin Carbon Films

Abstract: We describe monocrystalline graphitic films, which are a few atoms thick but are nonetheless stable under ambient conditions, metallic, and of remarkably high quality. The films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands, and they exhibit a strong ambipolar electric field effect such that electrons and holes in concentrations up to 10 13 per square centimeter and with room-temperature mobilities of ∼10,000 square centimeters per volt-second can be induced by applying gate voltage.

Carbon Nanotubes--the Route Toward Applications

Abstract: Many potential applications have been proposed for carbon nanotubes, including conductive and high-strength composites; energy storage and energy conversion devices; sensors; field emission displays and radiation sources; hydrogen storage media; and nanometer-sized semiconductor devices, probes, and interconnects. Some of these applications are now realized in products. Others are demonstrated in early to advanced devices, and one, hydrogen storage, is clouded by controversy. Nanotube cost, polydispersity in nanotube type, and limitations in processing and assembly methods are important barriers for some applications of single-walled nanotubes.
