Better Solar via Photonic Crystals

Yvonne Carts-Powell

Researchers at the Massachusetts Institute of Technology (MIT, U.S.A.) report designing a solar thermophotovoltaic system with a photonic crystal layer to trap and reflect light at the absorber.

A solar power system with a calculated overall system energy conversion efficiency of 37 percent uses a thermophotovoltaic (TPV) device design with no solar concentrators. Peter Bermel and other researchers at the Massachusetts Institute of Technology (MIT, U.S.A.) report designing a photonic crystal layer to trap and reflect light at the absorber. This makes the system much more efficient. (Nano. Res. Lett. 6, 549).
