Transparency-Switching Materials for Reactive Sun Tracking: CPV for the roof-top market

Alfredo Alexander-Katz and Matteo Chiesa with Harry Apostoleris

This grant is funded by the MIT Masdar Institute Cooperative Program

As the sun moves, roof-top PV solar panels lose efficiency, if they do not track the sun. This project is developing self-tracking solar concentrators that optimally concentrate the sun's rays as the sun moves. They are based on passive materials with no mechanical components and would increase the amount of energy generated from solar panels.
