硅太阳电池扩散方阻与栅线宽度匹配的研究

Study on the Match of Diffuse Square Resistance and Finger Width of Silicon Solar Cells

研究了扩散方块电阻及印刷栅线宽度变化对太阳电池电性能的影响,根据初步实验结果提出假设,通过进一步实验进行验证。结果表明:适当地提高扩散方阻、降低栅线宽度,有利于短路电流及效率的提升。但受限于串联电阻的增大,方阻及线宽存在一个最优值,通过Matlab软件建立模型进行模拟,求出最优解。证明了扩散方阻需要与栅线宽度很好地匹配才能达到理想的效果。

Researched is the influence of the change of diffuse square resistance and printing finger width on the electrical performance of solar cells. Firstly a hypothesis is proposed on the basis of preliminary experiment results, then it is verified by further experiments. The results show that improving diffuse square resistance and reducing the finger width appropriately can promote the short-circuit current and efficiency. But due to the increase of the serial resistance, the square resistance and finger width have an optimal value which can be resolved with the Matlab simulation model. It is proved that the diffuse square resistance and printing finger width need to match well to achieve an ideal effect.
