Dry-Etched Black Silicon Could Lower Solar Power Costs, Speed Industrial Production
HOUGHTON, Mich., Sept. 10, 2018 — One approach to improving solar cell efficiency is to shift to nanostructured silicon (black-Si, or b-Si), which has been shown to decrease reflective losses in multicrystalline silicon (mc-Si) wafers and prevent cell power conversion efficiency degradation. Researchers at Michigan Technological University analyzed the economic potential for industrial application of dry-etched b-Si. They found that the increase in the overall cell processing costs resulting from the addition of steps for the
Light-Harvesting Membranes Heat, Desalinate Water in One Step
HOUSTON, June 27, 2018 — A Rice University-led team will conduct further development and field testing of a desalination technology that uses nanoparticles and sunlight to treat water, with help from a $1.7 million grant from the Department of Energy (DOE). The technology,...
Optically Based T-Sensor Could Be Used in Manufacturing, Biomedicine
SÃO PAULO, Jan. 24, 2018 — A temperature-sensor (T-sensor) has been developed that is capable of precisely measuring temperatures in a wide band — between 80 Kelvin (-190 °C) and 750 Kelvin (476 °C). The ultrasensitive sensor, created in the laboratory by researchers at the...
Energy-Efficient Frequency Comb Could Be Used for Quantum Encryption
LOS ANGELES, Jan. 15, 2018 — A new design for a frequency comb that requires 1,000 times less power than traditional combs uses organic molecules to generate combs in ultrahigh-Quality Factor (ultra-high Q) microcavities. A University of Southern California (USC) research team...
Insight into Glass Formation Could Lead to Coatings, Other Applications
PHILADELPHIA, Sept. 18, 2017 — To better understand the optical properties of stable glasses, and whether they are analogous to the properties of naturally aged glasses, researchers developed perfectly round molecules that retain their three-dimensional shapes and do not...
Tunable Nanoparticle Layer Switches Between ‘Mirror,’ ‘Window’
LONDON, Sept. 13, 2017 — Researchers have made a reversible electrotunable filter that can change between a reflective ‘mirror’ and a transmissive ‘window’. This discovery could help scientists create special materials whose optical properties could...
Novel Crystal Structure Could Be Used to Build LEDs, Lasers
TALLAHASEE, Fla., Feb. 2, 2017 — The discovery of a one-dimensional crystal structure that is highly photo luminescent could help facilitate the development of novel applications for optoelectronic devices such as LEDs, photovoltaic cells and lasers. The crystal is an...
