- The screen-printed Al-back surface field (Al-BSF) is widely used now to reduce the back surface recombination velocity ( S b) and improve the efficiency of silicon solar cells. 铝背场能够有效降低电池背表面复合速率,提高转换效率,是商品化晶体硅太阳电池普遍采用的主要背表面钝化结构。
- A simple model is used to calculate the EBIC profile and to fit with the experiment data, then the diffusion length and surface recombination velocity are obtained. 给出一简单模型 ,对GaP样品n区的EBIC线形进行计算 ,拟合实验曲线 ,得出少子扩散长度和表面复合速度
- Depending on the image method and point source approximation method, the physic model was established, and the formula of photo-current versus surface recombination velocity was obtained. 导出了光电流与表面复合速率相应关系的计算公式，确定了可进行电量测量的实验装置。
- Simultaneously, defects in the passivation layer of the device surface are also increased with the increasing of the baking temperature and also the surface recombination velocity. 同时芯片表面钝化层内的缺陷数目也在温度作用下增加，引起芯片表面复合速度增加。
- So the back surface recombination velocity S b begins to strongly influence solar cell performance when the ratio of minority carrier diffusion length to device thickness approached or exceeds unity. 而当少数在流子的扩散长度大于硅片厚度时,电池片上下表面的复合速率对效率的影响显得更加重要。
- surface recombination velocity (S.R.V.) 表面复合速度
- effective recombination velocity 有效复合速度
- From the experiment results and the normalization results, the surface recombination velocities of silicon pn junction were obtained. 通过测量结果和计算结果的归一化比较，获得了其表面复合速率。
- Otherwise, wide pulse and slow falling edge can cause the errors of surface recombination velocities and bulk lifetime extracted from the photoconductive decay curve. 否则脉冲光过长的脉宽和下降沿将对光电导衰减曲线中进一步分离出的表面复合速度和少子体寿命结果造成误差。
- For the samples less influenced by the surface conditions (for example, shorter bulk lifetime or lower surface recombination velocities), the requirement of pulse width can be not strict. 若样品受表面状况影响较小时（如体寿命较低或表面复合速度低时），则可对两种理想脉冲光源的要求适当放宽。
