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7.2 K.研究结果为光伏组件的热管理提供了一种新方法.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 7.2 K when applying the biomimetic structure to photovoltaic modules,which provides a new method for thermal management of photovoltaic modules.
