p区 meaning in English

p-region
pregionp

In this design , the double graded doping solar cell accumulates the minority carriers with the drift field , which is located at the whole graded space . this means that the accumulation of minority carriers doesn ’ t depend on the above conditions
采用与众不同的通过在p区和n区都采用梯度掺杂这样一个所谓双梯度掺杂,在整个有源层获得高达104v / cm的漂移电场。
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。
