摘要
为探索去离子水和裸聚光硅电池间的相互作用机理及温度对此相互作用的影响,设计了去离子水浸没冷却裸聚光硅电池实验。实验结果表明,随着浸没时间的推移,裸聚光硅电池的电特征变化很小,主要取决于电池的表面结构和操作温度;裸聚光硅电池实验用去离子水的电导率在65℃下的变化比在常温下的变化大;但其光谱透过率的变化不会影响电池的输出。且后续的测试进一步表明去离子水不会破坏裸聚光硅电池,但电池减反射层和金属栅线等由于存在缺陷在去离子水中会影响电池的性能。
Direct de-ionised （DI） water immersion cooling has been verified to be an effective method of managing the operating temperature of concentrator silicon solar cells. However, the stable electrical performance is difficult to be achieved. In order to explore the interaction mechanism between DI water and bare silicon CPV cell self, as well as the temperature effect on the interaction, the bare silicon CPV ceils immersed by DI water test was designed. Long term immersion results showed that the electrical characteristics of hare silicon CPV cells have only a minor change with DI water immersion, which depends on the surface structure of the concerned ceils and working temperature. The electrical conductivity （EC） of DI water at 65 ℃ increased strongly with immersion time compared with that of DI water exposures at room temperature. The change in optical transmitance of the DI water for immersion bare silicon CPV ceils can not affect the electrical output of the ceils. The following test demonstrated that DI water is unlikely to damage the bare silicon CPV cell, but anti-reflection coating or contact fingers may have some defects, affecting the cell performance.
