Extreme Light Trapping
A silicon solar cell harvests the energy of the sun as light travels down through light-absorbent silicon. To reduce weight and cost, solar cells are thin, and while silicon absorbs visible light well, it captures less than half of the light in the near-infrared spectrum, which makes up one-third of the sun’s energy.

L.E.D. A History of the Future of Light
The new book by veteran technology journalist Bob Johnstone entitled L.E.D. A History of the Future of Lighting is a detailed account of the radically changing lighting industry. Chapter 15 Selling Darkness includes an overview of LESA and its research vision of lighting systems that think. The book is published by CreateSpace and is available via Amazon.

Recent advances in solid state lighting technology are enabling the development of ‘designer’ crops, according to Rensselaer Polytechnic Institute plant physiology expert Dr. Tessa Pocock, who serves as a senior research scientist at the Center for Lighting Enabled Systems & Applications (LESA). The impact of lighting on plants is the core focus for Pocock, who conducts research in both academic and industry settings around the mechanism of photosynthesis on plant development and regulation by light for traditional greenhouse crops and the emerging field of medicinal plants. Recently, Pocock and her team received a $25,000 grant from Dr. William Beers, Black Belt/Senior Systems Engineer at Current, powered by GE, to support continued work on sensing and signaling in plants.

LESA graduate Jessica Morrison was chosen as one of ten innovators in Cohort Three of Cyclotron Road, an incubator at Lawrence Berkeley National Laboratory that aims to bridge the science-to-product gap by investing in energy entrepreneurs through its two-year fellowship program. Dr. Jessica Morrison received her PhD in Physics from Boston University in 2016 and has since founded Helux Lighting as a spin-off of her work at LESA on beam-steering micro-mirrors. Applicants must go through a rigorous four-month long selection process. The ten innovators of Cohort Three represent eight universities across the US. The Cyclotron program innovators will begin their journey in May, 2017.

LESA, Cornell and NYSERDA announces the launch of a multidisciplinary consortium to reduce electricity use in greenhouses up to 70%. Greenhouse Lighting and Systems Engineering (GLASE), a seven-year $5 million project funded by NYSERDA, is being launched to transform the way greenhouses operate reducing both energy cost and carbon footprint. Dr. Tessa Pocock, Senior Research Scientist at LESA will lead the work at Rensselear.

LESA Alum Dr. Jessica Morrison has formed a startup, Helux Lighting, Inc to bring dynamic optical control to the market through microtechnology developed at Boston University. These micro-mirrors are an example of micro-electromechanical systems (MEMS) that can steer a beam of reflected light by applying a voltage. The tiny mirrors steer light faster that the human eye can detect and facilitate rapid control over light position, brightness, and illumination area. The competitive advantage of Helux technology is a tenfold reduction in size and lower cost when compared to existing mechanical systems for light control.
Renowned LESA Researcher Awarded Visiting Scholar Designation at Cornell
May 8, 2017, Dr. Tessa Pocock was awarded the Robert W. Langhans Visiting Scholar at Cornell University, School of Integrative Plant Science. Each year this Visiting Scholar Program brings a renowned scientist in greenhouse technology and management to lecture and interact with students over the course of several days to their Ithaca campus. This year Dr. Pocock will spend May 8-10 on their campus and will provide a lecture entitled “Light Matters: Sensing and Signaling in Plants”. Dr. Pocock, Senior Research Scientist at LESA, is a world-renowned speaker and researcher on plant photosynthesis and plant development and regulation by light for traditional greenhouse crops and the emerging field of medicinal plants.

Chaitanya Ullal, assistant professor of materials science and engineering, and a Faculty member of the ERC, has won a Faculty Early Career Development Award (CAREER) from the National Science Foundation (NSF). He will use the five-year, $556,091 award to study the structure of hydrogels—jelly-like materials that have some of the properties of solids, but are largely composed of water. The CAREER Award is given to faculty members near the beginning of their academic careers and is one of the most competitive and prestigious awards given by the NSF to junior faculty.

Professor Connor Recognized as Innovator at 2017 ECEDHA Annual Conference
On Monday, March 20, 2017, Professor Kenneth Connor (RPI) was presented with the “Innovative Program Award” at the 2017 ECEDHA Annual Conference in Miramar Beach, Florida. Don Millard (NSF) summarized Ken’s contributions well, “Ken is loved by many and is a true innovator: he has the intellect and motivation to seek and see space that others don’t, he is not afraid to break from the norm, using past traditional wisdom.” This award is given to individual(s) or department(s) […]

Sensing and Signaling Networks in Plants. What’s Light Got to Do with It? Is the title of Dr. Tessa Pocock’s presentation March 15, 2017 at the Phosphor Global Summit to be held at the San Diego Marriott La Jolla. Recent advances in lighting technology are enabling the development of ‘designer’ crops. Light is the primary energy source required for crop growth and development but it also contains signals that shape the plant down to sub-cellular levels. The assessment of lighting and spectral distributions on photosynthesis, growth and phytochemical value will be presented.
