半切电池凭借在组件级别提高功率输出的潜力，必将成为2018年的关键技术趋势。数家一线制造商在最近几个月内纷纷推出了采用该技术的产品。
半切电池有时被称为半片电池，与“标准的”全电池相比具有许多优点。最主要的优势在于减少了电池到组件的功率输出损耗。Sinovoltaics集团的董事总经理Dricus de Rooij解释说，电池到组件的功率损耗“通常正比于电流的平方乘以电阻”。
它的另一个优势是每个主栅所承载的电流量也减少了一半，从而导致电阻下降，效率提高。
“每个制造商的实际效率提高各有不同，在1.5-3%的效率范围之内，这非常重要，”他补充道。
某些制造商还声称，半切电池组件具有其他一些优点，比如减少形成热点的可能性、包括更强大组件设计在内的结构优势、降低工作温度，以及分流电流的电池配置，以让组件的上下半部分基本上作为单独的组件来工作，从而减少内部电阻和部分组件阴影的影响。
在2月的东京国际光伏能源展（PV Expo）期间，韩华Q Cells首次在日本市场推出了其“旗舰型”组件。Q.PEAK DUO采用了半切单晶硅电池和六个主栅电池互连，以315-330瓦的60个全电池配置（120个半切电池）提供输出。
