Review: Progress in solar cells from hydrogenated amorphous silicon

Christophe Ballif, Franz-Josef Haug, Michael Elias Stückelberger, Rémi Biron

Hydrogenated amorphous silicon (alpha-Si:H) has been used for decades doped and as intrinsic absorber layers in thin-film silicon solar cells. Whereas their effiency was improved for a long time by the deposition of higher quality absorber layers, recent i ...

UV imprinting for thin film solar cell application

Christophe Ballif, Céline Pahud, Franz-Josef Haug, Corsin Battaglia, Jordi Escarre Palou, Rémi Biron

UV imprinting is an interesting, low cost technique to produce large area thin film solar cells incorporating nanometric textures. Here, we review and present new results confirming that replicas of the most common textures used in photovoltaics can be obt ...

Improvement of the open circuit voltage by modifying the transparent ITO front electrode in amorphous n-i-p solar cells

Christophe Ballif, Jonathan Besuchet, Gilles Kratzer, Frank Jonathan Leresche, Franz-Josef Haug, Rémi Biron

At the front contact of thin film silicon solar cells, the junction between the p-doped window layer and the n-type transparent electrode results in a barrier that must be surmounted by the charge carriers. The barrier height is governed by the work functi ...

Window layer with p doped silicon oxide for high V-oc thin-film silicon n-i-p solar cells

Christophe Ballif, Céline Pahud, Franz-Josef Haug, Jordi Escarre Palou, Rémi Biron

We investigate the influence of the oxygen content in boron-doped nanocrystalline silicon oxide films (p-nc-SiOx) and introduce this material as window layer in n-i-p solar cells. The dependence of both, optical and electrical properties on the oxygen cont ...

NANO-IMPRINT TECHNIQUE FOR BACK REFLECTOR IN HIGH EFFICIENCY N-I-P THIN FILM SILICON SOLAR CELLS

Christophe Ballif, Céline Pahud, Karin Söderström, Franz-Josef Haug, Jordi Escarre Palou, Rémi Biron

In this contribution, the replication of nano-textures enhancing the short circuit current of thin film silicon solar cells onto low cost substrates (glass or PolyEthylene Naphtalate (PEN)) is studied. Optical and morphological analysis is performed to ass ...
