The iconic MIT home page Spotlight features a daily-changing image and design that focuses on advances in research, technology and education taking place at the Institute. Though some Spotlights do run multiple days - for example Friday's spot usually runs through the weekend, we work very hard to maintain the daily-changing tradition. We've combed our servers and have compiled a digital archive of the Institute home page through the years - well over 2000 images. Enjoy!

Today’s Spotlight uses an image, by Felice Frankel, of a nanophotonic solar thermophotovoltaic device as viewed from the perspective of the incident sunlight. Reflective mirrors boost the intensity of light incident on the carbon nanotube absorber array, enabling the device to reach high temperatures and record‑setting efficiencies.

A new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high‑temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the energy for later use, the researchers say.

The MIT home page Spotlight showcases the research, technology and education advances taking place at the Institute every day.

What makes it as a Spotlight image is an editorial decision by the MIT News Office based on factors that include timeliness, promotion of MIT's mission, the balance of interest to both internal and external audiences, and appropriateness.

We do welcome ideas and submissions for spotlights from community members, but please note we are not able to accommodate all requests. We are unable to run event previews or promotions as spotlights; for those looking to promote an event, we are happy to include your listing as an event headline on the homepage (when space is available) and you are free to submit an Of Note to the MIT News office. For more information, e-mail the spotlight team.
