    • Provided are methods and systems for treating shunts on solar cell substrates. Also provided are solar cells including such substrates. A shunt detected on a substrate proximate to a metallized grid pattern is electrically disconnected from at least the bus portion of the grid, which reduces shunt's impact on performance on the solar cell. An antireflective layer may be disposed between the shunt and a portion of the grid extending over the shunt. The exposure pattern of a photoresist used to form the antireflective layer may be adjusted accordingly to achieve this result. In some embodiments, the metallized grid may be modified by adjusting the exposure pattern of a photoresist used to form this grid. The grid may be modified to avoid any contact between the grid and the shunt or to disconnect a portion of the grid contacting the shunt from the bus portion area of the grid.
    • 提供了用于处理太阳能电池基板上的分流器的方法和系统。 还提供了包括这种基板的太阳能电池。 在靠近金属化栅格图案的衬底上检测到的分路与栅格的至少总线部分电连接,这降低了分流对太阳能电池性能的影响。 防反射层可以设置在分流器和在分流器之间延伸的网格的一部分之间。 可以相应地调整用于形成抗反射层的光致抗蚀剂的曝光图案以实现该结果。 在一些实施例中,可以通过调整用于形成该栅格的光致抗蚀剂的曝光图案来修改金属化栅格。 可以修改电网以避免电网和分流器之间的任何接触,或者使接触分流器的电网部分与电网的总线部分区域断开。
