ABSORBENT MATERIAL AND SOLAR PANEL USING SUCH A MATERIAL |
| 摘要 |
The invention concerns a multilayer material comprising at least:
a support having a reflectance R higher than 80% for radiations of wavelengths higher than 5 μm,a selective layer comprising a combination of Vanadium oxides VO2 and VO2O2n+/−1, with n>1, said selective layer having an absorbance higher than 75% for radiations of wavelengths comprised between 0.4 and 2.5 μm, regardless of the temperature T, and having, for radiations of wavelengths comprised between 6 and 10 μm, a transmittance Tr such that:
Tr>85% for T<Tc, a critical temperature,20%≦Tr≦50% for T>Tc.;Application to the production of thermal solar panels having a low stagnation temperature and high performance. |

1. A multilayer material comprising at least:
a support having a reflectivity R higher than 80% for radiations of wavelengths higher than 5 μm, a selective layer having a thickness comprised between 100 and 500 nm, said selective layer comprising a combination of vanadium oxides VO2 and VnO2n+/−1, said selective layer having an absorbance higher than 75% for radiations of wavelengths comprised between 0.4 and 2.5 μm, regardless of the temperature T, and having, for radiations of wavelengths comprised between 6 and 10 μm, a transmittance Tr such that:
Tr>85% for T<Tc, a critical temperature,20%≦Tr≦50% for T>Tc. |
