concentration cell 濃差電池。

concentration ring

On the base of these theory calculations , we passivated the front - surface both of different surface doping concentration solar cells by a thin layer of thermally grown sio2 . the results show that the in heavy surface doping concentration cell is lower compared to the cell in light surface doping concentration . the majority of improvement in comes from the emitter surface passivation 接著采用sio2作為鈍化膜,從實驗上比較了在不同表面濃度下單晶硅太陽電池的鈍化效果,結果表明在高表面濃度下其開路電壓比低表面濃度下的開路電壓低,這開路電壓的提高主要來源于降低了前表面復合。

As a comparison , ba1 . 03ce0 . 8gd0 . 2o3 - was synthesized by sol - gel method . among these samples , nonstoichiometric samples were synthesized for the first time . the research work involved : the crystal phase of the sinters were determined by xrd ; ionic conduction under different experimental atmospheres was measured by gas concentration cells ; performances of hydrogen - air fuel cells with the sinters as electrolytes and porous pt as electrodes were measured 用粉末x射線衍射儀鑒定它們的結晶相;在( 600 1000 )范圍內,以燒結體作為電解質隔膜,多孔性pt黑為正、負電極, pt - rh合金網為集電極,分別組成氫濃差電池、氧濃差電池及氫?空氣燃料電池并測定了它們的性能,研究了不同氣氛下樣品的離子導電特性及影響燃料電池性能的因素。

Ozone enhancement was observed in the lower troposphere over kunming on 21 march 2001 using electrochemical concentration cell ozonesondes 摘要2001 - 03 - 21在昆明用電化學臭氧探空儀探測到了對流層低層異常的高濃度臭氧分布。
