Influence of abrasive concentration on the qualiy of wire-sawn silicon wafers

Christophe Ballif, Mathijs Pieter van der Meer, Adrien Bidiville

The sawing parameters have an impact on the depth of the defects in the wafers, and hence on their mechanical strength. However, as sawing is a highly complex system, the wafering industry is still relying on a “trial and error” approach to improve the saw ...

Opto-electronic properties of rough LP-CVD ZnO:B for use as TCO in thin-film silicon solar cells

Christophe Ballif, Sylvie Faÿ

Polycrystalline Boron-doped ZnO films deposited by low pressure chemical vapor deposition technique are developed for their use as transparent contacts for thin-film silicon solar cells. The size of the columnar grains that constitute the ZnO films is rela ...

Heterojunction solar cell efficiency improvement on various c-Si substrates by interface recombination modelling

Christophe Ballif, Luc Fesquet

High efficiency Si heterojunction (HJ) solar cells must exhibit low interface recombination, as it limits the cell open circuit voltage (VOC). The study of the interface recombination of various a-Si:H/c-Si lifetime test samples gives insight into the reco ...
