High efficiency process development for defect-rich silicon wafer materials

159 Seiten, Dissertation Universität Konstanz (2012), Softcover, B5

Zusammenfassung / Abstract

The silicon wafer is a major cost driver for solar cells based on crystalline silicon.

This work describes the influence of different solar cell processing steps on a variety of cheap but defect-rich alternative multicrystalline silicon wafer materials.

A high efficiency lab-type solar cell process is presented, which allows the determination of the solar cell efficinecy limit for a very broad range of different silicon wafer materials.

The process features a single sided front texture, tunable defect engineering via gettering and hydrogenation and a very low thermal budget dielectric rear side passivation with local laser fired contacts.
