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.

Circadian, Sleep and Neurobehavioral Performance Engineering @ LESA
Human circadian rhythm regulation is linked to many physiological processes, including sleep. Circadian disruption is known to have negative impacts on health and may lead to lower human performance and higher risk of failure during critical tasks. By understanding the relationships between human circadian processes, sleep processes, and cognitive performance, improved management of lighting and task scheduling can be developed to favorably impact overall human health and performance.

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.

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.
