Abstract

The two-phase MoO₂/Mo₄O₁₁ NPs were prepared by dry reduction of MoO₃ NPs, which are highly regarded for their excellent solar photovoltaic conversion performance and excellent thermal stability. The materials were tested and found to have less than 10 % reflectance and up to more than 95 % absorption in the range of 200–2500 nm of the AM1.5 global standard solar spectrum. The two-phase MoO₂/Mo₄O₁₁ NPs rapidly warmed up from room temperature to the maximum equilibrium temperature of 50 °C in 20 s under one solar light intensity. And no photothermal degradation occurred under five photothermal cycle tests. The two-phase MoO₂/Mo₄O₁₁ NPs were combined with the temperature difference power generation technology to construct a photothermal power generation device. Under a standard sunlight intensity, the voltage can reach 0.27 V, and the maximum voltage that can be achieved in the photothermal power generation cycle test is almost the same.

MoO2/Mo4O11光热纳米材料的太阳能发电性能

通过对MoO3 NPs的干还原制备了两相MoO2/Mo4O11 NPs， MoO3 NPs具有优异的太阳能光伏转换性能和优异的热稳定性。对这些材料进行了测试，发现在AM1.5全球标准太阳光谱的200 - 2500nm范围内，反射率小于10%，吸收率高达95%以上。在一个太阳光照强度下，两相MoO2/Mo4O11 NPs在20 s内从室温快速升温到最高平衡温度50℃。5次光热循环试验均未发生光热降解。将两相MoO2/Mo4O11 NPs与温差发电技术相结合，构建光热发电装置。在一个标准的阳光强度下，电压可以达到0.27 V，与光热发电循环试验中所能达到的最大电压几乎相同。
