| 摘要: | 对当前晶硅太阳电池的太阳吸收特性进行了太阳光谱分析, 并在此基础上提出一种基于撒哈拉银蚁仿生结构的热管理方法, 该仿生结构由氧化物-金属-氧化物Oxide-metal-oxide(OMO)和表面具有微纳结构的聚二甲基硅氧烷Polydimethylsiloxane(PDMS)薄膜共同组成, 可通过热辐射进行表面散热, 同时也能显著地反射近红外波段的太阳光, 进一步降低表面温度. 理论计算结果表明, 将该冷却器应用于光伏组件可使电池温度降低约7.2K. 研究结果为光伏组件的热管理提供了一种新方法. |
| Abstract: | Heating in solar cells has significantly negative effects on the conversion efficiency and reliability, resulting in a shortened lifetime. According to the analysis on the solar spectra in which silicon solar cells work, this paper proposes a thermal management strategy inspired by Saharan silver ants. The biomimetic structure is composed of an oxide-metal-oxide (OMO) and a micro/nano-structured polydimethylsiloxane (PDMS) film. It can radiate heat through thermal radiation while reflecting the near-infrared sunlight to cool the surface temperature. Theoretical calculations reveal that the temperature of solar cells can be reduced by about 7.2K when applying the biomimetic structure to photovoltaic modules, which provides a new method for thermal management of photovoltaic modules. |
