早在 2012 年就有厂商致力于 PERC 电池的效率提升、解决其
量产问题。由于一条电池片产线投入 PERC 技术额外增加的设备成
本不超过一千万美金,比起 N 型技术便宜很多,且能直接使用原本的
硅片,每瓦制造成本只多出 4 美分,效率却能提升 0.6%~1%,使得不
少台湾厂商在 2013~2014 年间大举投入,台湾从而成为目前
PERC 技术在产能及效率面的领先区域。
中国一线垂直整合大厂在确定了 PERC 技术确实能稳定量产之
后,亦不愿在高效领域落后,尤其阿特斯、晶澳、天合光能都有计划
在今年有较大规模的投入,若导入过程顺利,中国厂商要在年底一
举超过台湾现有的 1GW PERC 产能,也并非难事。但高效市场并
非产能之争,效率及质量的稳定性才是最难控制的部分。
厂商在导入 PERC 技术时,会因为导入的机台、镀膜的材料、激
光钻孔的方式、浆料的选择等让后续量产的效率、良率等有些微差
异。其中,台湾厂商旭泓由于导入时间早,目前仍是 PERC 技术的
领头羊,PERC产能规模、量产效率及光衰的控制在台湾无人能出
其右。旭泓目前的量产效率在 20.5% 左右,并计划在今年将效率提
升至 21%,成为各家 PERC 厂商竞相追赶的指标。
虽 PERC 成为 P 型电池效率能够继续提升的主要方法,但光衰
问题却始终是其与 N 型电池比较时的致命伤。目前除了旭泓之外
,其余电池片厂商仍尚未找到光衰问题的解法,产出的 PERC 电池
光衰高达 3~5%,也使得 PERC 电池需求不如预期。
今年第一季,单晶产品需求冷清,使得单晶硅片价格首当其冲,自
去年每片US$1.16 跌至 US$1.10 的保卫关卡。高效的 PERC 产品
价格亦大幅跌落,虽原先预期继续扩充 PERC 产能的厂商并没有
停下脚步,但却让计划今年量产 PERC 电池的厂商更加犹豫,故
光衰问题的解决之道、单晶市场的回温将会是今年电池片厂商持
续关切的议题。由于光衰问题在硅片区段能改善的情况有限,故目
前厂商只能先期望各设备商推出解决方案,否则 PERC 产品的需
求将难以再扩大。
