Examining cost of ownership of crystalline-silicon solar-cell wet processing: texturization and clea


By Ismail Kashkoush, Vice President of Technology, Akrion Systems; David Jimenez, President and Cofounder, Wright Williams & Kelly

This paper, the second in a series covering cost of ownership studies for photovoltaics [1], examines the need for saw damage removal and the follow-on processes of precleaning, texturization, and cleaning. The process considerations for wet and plasma approaches are further discussed before taking a detailed look at texturization using random pyramid formation. The paper will conclude with a view of current and future wet process techniques and a cost of ownership case study using Akrion Systems’ GAMA-Solar as an example.
