Thermophotovoltaic System Exhibits Better Absorption
CAMBRIDGE, Mass., Oct. 1, 2014 — A 2-D photonic crystal could prove key in advancing the absorption and use of solar energy.
The new material, developed by researchers at MIT, is a metallic-dielectric crystal that absorbs sunlight from a wide range of angles and can withstand extremely high temperatures. The material has already shown that it can withstand 1000 °C over 24 hours without severe degradation.
With the thermophotovoltaic device, the sunlight’s energy is first converted to heat, causing...
