Screen‐Printed Front Junction n‐Type Silicon Solar Cells

This chapter aims to provide students/engineers/scientists in the field of photovoltaics with the basic information needed to understand the operating principles of screen‐ printed front junction n‐type silicon solar cells. The relevant device fabrication process‐ ing is described, from texturing, diffusion, passivation and antireflection coating, to screen‐ printed and fired‐through metallization as well as the technologies that are currently used for most industrially produced solar cells. A brief description of the characterisation approaches is given and discussed for an understanding and analysis of the loss mechanisms in a finished cell, including resistance loss, recombination loss, and optical loss. The application of advanced cell concepts and the improved technologies for further increasing cell efficiency, such as selectively doping structure and tunnel oxide passivated contact, are addressed for screen‐printed front junction n‐type silicon solar cells.
