晶体硅太阳电池用电极设计的研究

Study of the Screen Design on Crystalline Cell Fabricating

随着诸如新型用气体完成而不是化学药品的制绒方法等新技术的改进和适用于更细的细栅宽度的导电浆料的替代,多晶电池的效率变得越来越高。多晶电池的常规工艺顺序有酸化学试剂制备的绒面,磷扩散,边缘绝缘,减反射膜的沉积,背面银/铝浆、铝浆的印刷及正面银浆的印刷。本文通过几组实验数据来讨论不同的丝网设计与浆料特性的匹配数据,从而得出最优的印刷质量和电池效率。

With the completion of such a gas instead of a new chemical method for texturing of new technology to improve and apply a thin gate width finer conductive paste alternative, polycrystalline become higher cell efficiency. Polycrystalline cells with conventional process sequence suede acid chemical reagent preparation, phosphorus diffusion, edge insulation, anti-reflection film deposition, backside silver / aluminum paste, aluminum paste printing and front silver paste printing. In this paper, several sets of experimental data to discuss the different properties of the screen design and the sitar）, matching data, so as to arrive the best print quality and cell efficiency.
