摘要
采用喷墨打印印制太阳电池具有碎片率低、栅线高宽比大、太阳电池转换效率高等优点。为提高栅线打印精度和高宽比，采用有限元技术对压电式打印喷头进行建模，并采用一款新型基于生命周期理论的菌群觅食算法对打印喷头的驱动波形参数进行优化，以获得期望的液滴特性（体积、速度和卫星液滴数量），数值仿真结果显示此算法性能优良，液滴状态模拟仿真结果及液滴实测结果证实上述液滴状态优化仿真方法可准确获得期望液滴特性。
Ink-jet printing solar cell has some advantages, such as low fragment rate, high depth/width ratio and high photoelectric conversion efficiency. In order to improve the high depth/width ratio and printing precision, the finite element technology is adopted to model the piezoelectric printheads, and a new bacteria foraging algorithm with a lifecycle strategy is proposed to optimize the parameters of driving waveform for getting the desired droplet characteristics. Results of numerical simulation showed that such algorithm has a good performance. Additionally, the droplet jetting simulation results and measured results confirmed such method precisely gets the desired droplet characteristics.
