结势垒 meaning in English

junction barrier

We define the recombination time of excess electrons in p field as the minority carrier lifetime . in theory , we developed the equation between excess minority carriers lifetime and the open - circuit voltage decay ; moreover , the effect of capacitance to general open - circuit voltage is also investigated . both different efficiency solar cells are measured by the method and showed the relations between the minority carrier lifetime and the performance of solar cells , which provides great useful guidelines for fabricating high - efficiency silicon solar cell in industry
根据太阳电池的工作原理，详细地论述了用脉冲光源照射n / p结太阳电池时光电压的产生，理论上给出了注入p区的电子复合带来的开路电压与少子寿命的关系，也研究了n / p结势垒电容放电对开路电压衰减的影响关系，推导了利用开路电压随时间衰减的关系来测量少数载流子寿命的理论公式。
