Thermophotovoltaic System Exhibits Better Absorption

Facebook X LinkedIn Email
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 the material to glow and emit light that can be converted to electrical current. Creating the new material...Read full article
