Silicon heterojunction solar cells: Techno-economic assessment and opportunities

Perspective Year: 2022 DOI:https://doi.org/10.1016/j.joule.2022.02.009

Authors: Arsalan Razzaq, Thomas G. Allen, Wenzhu Liu, Zhengxin Liu, Stefaan De Wolf

Arsalan Razzaq and colleagues from KPV-Lab recently published their perspective in Joule, discussing the techno-economic barriers for the industrial adoption of silicon heterojunction technology. This work highlights critical areas that need to be addressed for enabling terawatt-scale silicon heterojunction deployment.
