SERIS的科学家们拿着采用其新型DWS工艺制造的电池和晶片。

新加坡太阳能研究所(SERIS)的科学家们开发出一种新型湿化学方法，能利用金刚石绳锯技术切割多晶硅片，并随后织构以降低反射率。
这一湿化学法以纳米特征尺度刻蚀晶片表面，从而增加了光线反射表面的次数及被晶片材料吸收的机会。该工艺使用专利性化学品，具有低成本性和可扩展性，且极易被集成入电池生产线。
SERIS认为，相较于“黑硅”工艺，其新工艺能给生产厂家提供更多的益处。表示他们的技术“更简单、更价廉，且无金属，可以达到20%以上的电池效率”，有潜力成为被多晶硅太阳能电池制造商广泛使用的主流织构技术。
据SERIS表示，这一工艺已获得了几家一线厂商的认可。该机构准备与这些厂家密切合作，将其扩大到大型生产线。
