石墨烯膜实现超高压太阳电池阵的静电防护

Graphene film achieves electrostatic protection of ultra-high voltage solar array

针对空间电站太阳电池阵容易在超高压工作下出现静电损伤的问题,通过研制具备高透过率和导电性的石墨烯透明导电膜,实现了全柔性太阳电池组件表面零电位,达到静电泄放的目的。在750 V串间高压的试验条件下,石墨烯膜封装的全柔性太阳电池组件未出现放电现象,电性能未发生变化,证明了石墨烯膜在超高压条件下的静电防护能力。

Aiming at the problem that the solar array of space power station is prone to electrostatic damage under ultra-high voltage,a graphene transparent conductive film with high transmittance and conductivity is developed to realize zero potential on the packaging surface of the fully flexible solar cell module,and achieve the purpose of charge release.Under the experimental conditions of 750 V ultra-high voltage,the fully flexible solar cell modules encapsulated by graphene film did not show electrostatic discharge and the electrical properties of the solar cell modules did not change,which proved the ability of graphene film in electrostatic protection under ultra-high voltage condition.
